I didn’t, unfortunately, keep track of this class of students until fairly recently; hence, my records are incomplete with respect to this point. Northwestern University Center for Atom-Probe Tomography I founded the Northwestern University Center for Atom-Probe Tomography (NUCAPT) in August 2004. NUCAPT is a unique university core facility at Northwestern University and the US, which has had and will have major significant impacts on the research efforts of undergraduate work-study students, senior theses, research experiences for undergraduates (REU), M.S., Ph.D. and postdoctoral students. Additionally, since 2005 underrepresented groups of students have employed the services of NUCAPT. In the department of materials science and engineering at Northwestern six professors and their graduate students (MS, PhD and postdoctoral) make extensive use of NUCAPT. Additionally, NUCAPT has users from other US universities, national laboratories, US companies, as well as international universities and companies. As of September 15th, 2015, NUCAPT is part of the NSF National Nanotechnology Coordinated Infrastructure (NNCI), which brings it into contact with an even wider range of researchers who are interested in performing APT experiments. NUCAPT has educated a large number of people in the US and abroad in the application of APT to a wide range of materials and materials science and engineering problems, which is extremely important for characterizing materials at the subnano- to nanoscale. There is no other university APT core facility in the US providing outreach to the extent that we are accomplishing this objective. My former Ph.D. students have established atom-probe tomographic laboratories at the University of Michigan, Ann Arbor, Michigan; Naval Research Laboratory (NRL), Washington, DC; Pacific Northwest National Laboratory (PNNL), Richland, Washington; Sandia National Laboratory, Livermore; and the Swiss Federal Institute of Technology (ETH), Zurich, Switzerland.

NUCAPT serves as both a research and educational facility, continuing and extending a series of 120 Ph.D. theses, 49 postdoctoral studies, 32 undergraduate research projects, seven high school students from Evanston Township H.S., and external research projects from academia and

industry, who have utilized NUCAPT since 2005. NUCAPT originally employed a conventional 3D-APT and since January 4th, 2005 it operates a LEAP tomograph, which has been upgraded four times since then to include the newest technologies: the last upgrade includes a state-of-the art ultraviolet (wavelength = 355 nm) picosecond laser system installed in 20122. Additionally, we are continuously broadening the user base to serve the needs of academicians, postdoctoral and Ph.D. students, and industrial users in both the US and internationally. Because of the significant technical advantages of the UV laser-enhanced LEAP with high specimen-throughput and ultrafast data acquisition, we are able to serve the needs of a continuously growing user base. NUCAPT provides LEAP tomography instrument time, technical support, and analytical services to researchers from academia, national laboratories, and industry, in the US and internationally. Cooperative research projects have been performed with graduate and postgraduate students from the following institutions and are we are currently continuing and expanding these collaborations: Lehigh University; Washington University in St. Louis; University of Chicago; Akron University; University of Illinois at Urbana Champaign; Illinois Institute of Technology (IIT); Massachusetts Institute of Technology (MIT); University of California – Davis; Drexel University; Missouri University of Science and Technology; University of Tennessee-Knoxville; Florida State University (FSU); The Field Museum of Natural History, Chicago, IL; Argonne National Laboratory; Fermilab (FNAL); NASA Glenn Research Laboratory; Pacific Northwest National Laboratory (PNNL); Knolls Atomic Power Laboratory; Technion: Israel Institute of Technology; Ben-Gurion University of the Negev; Tel-Aviv University; the Hebrew University of Jerusalem, École Polytechnique, Montréal; Simon-Fraser University, British Columbia; Tohoku University (Japan); Max-Planck Institute for Microstructure Physics (Germany); and the following companies: NanoAl LLC; QuesTek Innovations LLC; AO Smith; EADS Germany (Airbus); Apple; First Solar; and Toyota Research Laboratories, Japan. Additionally, more than 17 international students have performed research in NUCAPT since 2012. European Union Marie Curie Fellow J. A. Coakley spent two years (2014 to 2016) in Seidman’s group at NUCAPT to conduct advanced studies of Ti- and Co-based alloys. And European Union Marie Curie Fellow Prof. Yaron Amouyal (currently associate professor at the Technion, Israel Institute of Technology, Haifa, Israel) spent three years working with me on nickel-based superalloys addressing the problem of “freckles” caused by problems associated with castings.

As of 2015/09, NUCAPT is part of the newly created SHyNE (Soft and Hybrid

Nanotechnology Experimental) research resource at Northwestern University with support from 2 Our LEAP4000X Si was upgraded in mid-October/mid-November 2017 to a LEAP5000XS, which makes it the complete equivalent of a brand-new LEAP5000XS; it is manufactured by Cameca Instruments Inc, Madison, Wisconsin. It has a straight time-of-flight mass-spectrometer and a detection efficiency of 80%, which is 60% greater than that of the LEAP4000X Si, and it also has an increased field-of-view as well as improved software for data collection. The source of funding for this upgrade is an ONR DURIP grant for $1,210,000, including Northwestern University’s contribution of $310,000. We are currently beta-testing version 4.0 of IVAS for Cameca.

the NSF National Nanoscience Coordinated Infrastructure (NNCI) program. SHyNE provides researchers from academia, small businesses, and industry researchers access to cutting-edge nanotechnology instrumentation and expertise, which includes NUCAPT. Our participation in SHyNE are helping with our outreach activities to the USA research community for cutting-edge nanotechnology research.

The education of high school, undergraduate, M.S., Ph.D., postdoctoral students,

professional researchers, and underrepresented minority and women students is facilitated via workshop style training units. The training units extend over 3-4 hours per session and cover: (1) theoretical background of atom-probe tomography; (2) practical use of the ultraviolet-laser-assisted LEAP tomograph; (3) analysis of data recorded using IVAS data analysis code; and (4) preparation of specimens using electropolishing and/or a dual-beam focused-ion beam (FIB) microscope.

The IVAS software package is continuously being developed by Cameca, Madison, WI.

We are interacting strongly with Cameca by providing their software developers with feedback, discussing new applications, and also providing them data analysis code we have developed. We are currently beta-testing version 4.0 of IVAS for Cameca. Cameca has agreed to co-sponsor these workshops by providing personnel to help run instruments and instructors to help teach the subject of APT.

NUCAPT has developed cutting-edge techniques for correlative studies that combine

multiple characterization techniques, such as TEM, EBSD, EDS and EELS, and properties measurements with APT on the very same specimen. NUCAPT has developed substantial know-how and expertise for these correlative APT studies.

At Northwestern University the NSF funded Nanoscience and Engineering Center and the Materials Research Science and Engineering Center have REU (Research Experience for Undergraduates) programs, which are aimed at women and underrepresented minority students, USA and Puerto Rico. Seidman and his research group have and will continue to supervise women and underrepresented groups of REU students from these programs and teach them how to perform LEAP tomography. In addition to supervising research projects for these diverse

groups we have and will continue to conduct lessons for REU/Materials Research Institute (MRI) students to teach them LEAP tomography and how it is employed for various research projects at Northwestern University and elsewhere.

In terms of undergraduate education and research projects, NUCAPT has attracted a

number of students through the NSF-REU programs, in addition to work-study and senior project students from the Department of Materials Science and Engineering, who perform their thesis projects in NUCAPT. Since 2008, the following undergraduate students have performed research at NUCAPT: T. Gyger; Ms. A. Werber; N. Kim; Y. Mao; X. Yin; A. Kuo, D. Cecchetti; M. Diaz (Hispanic); J. Johnson (African-American); Ms. Lillian Novak (Brown University); L. Crosby; V. Kulkarni; R. Schuld (Northwestern), J. Finamore (Colorado School of Mines); E. Hunt; P. Maris; J. Lin; Ms. Jennie Wang (Yale University.); and pre-doctoral students Ms. Ashley (Yanyan) Huang, M. Yildirim. Ms. I-Wen Hsieh, J. McKinney, D. Cecchetti, X. Yin, J. Lin and F. Cui performed research for their M.S. theses at NUCAPT.

The NSF Materials Research Institute (MRI) at Northwestern collaborates with

underrepresented colleges and universities; Morehouse College, Fisk University, Hampton College, University of Texas at El Paso and Alabama A&M University. The MRI has support to develop and establish a cyber-infrastructure called the International Virtual Institute (IVI), which has a number of capabilities for information dissemination and outreach activities. NUCAPT will use this feature to provide these colleges and universities with remote access for visualizing LEAP tomographic data. Additionally, the IVI is establishing a global research gallery, where the research posters are available for viewing. These will enhance further collaborative interaction for

Additionally, we will contribute to outreach programs to science teachers and college professors throughout the US via the Materials Word Modules (MWM) program at Northwestern – see http://Materialsworldmodules.org. Figure 1 summarizes the interactions and outreach programs at NUCAPT to educate and collaborate nationally and internationally on the topic of nanoscale materials characterization and development employing atom-probe tomography. SOME RESEARCH AREAS AND INTERESTS – PAST AND PRESENT Research topics: relatively recent and ongoing • As part of an Energy Frontier Research Center (EFRC) on the subject of thermoelectricity --

http://www.energyfrontier.us/sites/all/themes/basic/pdfs/RMSSEC.pdf -- we worked on bulk semiconducting thermoelectric materials whose nanostructures are optimized to increase the electrical conductivity and decrease the thermal conductivity. The thermal conductivity is decreased by precipitating a high number density of nanometer size precipitates, which increases the surface-to-volume ratio of matrix/precipitate interfaces and thereby enhances significantly the scattering of phonons. The electrical conductivity is increased by adding a dopant, for example, sodium in the PbTe-PbS system. We have applied atom-probe tomography to study the nanostructure: specifically, the compositions of the matrix and precipitates and the Gibbsian interfacial excesses of solute at matrix/precipitate interfaces as this affects phonon scattering compared to clean matrix/precipitate interfaces.

______________________________________________________________________________ • Scientific studies are being performed of model nickel-based superalloys, which are used to

fabricate turbine blades for commercial and military aircraft jet engines, and for turbine blades in land-based natural gas turbines used to generate electrical power. We are studying the temporally evolving microstructures on both nanometer and mesoscopic length scales. This research yields a scientific understanding of the kinetic trajectories leading to the development of the nano- and microstructures. We are basically studying the kinetics of a first-order phase transformation, which involves the decomposition of a face-centered-cubic (FCC) single-phase solid-solution into a two-phase alloy consisting of an ordered phase L12 (Ni3AlxCr1-x) phase and a disordered FCC matrix. The alloys being studied are Ni-Al, Ni-Al-Mo, Ni-Al-Cr, Ni-Al-Cr-Re, Ni-Al-Cr-W, Ni-Al-Cr-Re-W, Ni-Al-Cr-Ta, Ni-Al-Cr-Ru, Ni-Al-Cr-Ru, and Ni-Al-Cr-Re-W-Ru. The approach involves adding systematically one refractory element (Re, Ru, W, Ta) at a time to a base ternary reference alloy, Ni-Al-Cr, to understand how each elemental addition affects the ultimate microstructures. These alloys are studied using atom-probe tomography (APT), transmission electron microscopy (TEM), high-resolution electron microscopy (HREM), scanning electron microscopy (SEM), optical microscopy, and microhardness measurements. An important result of these studies is that the mechanism of coarsening is via a coagulation-coalescence mechanism and not the classic Lifshitz-Slyozov-Wagner (LSW) mechanism, which is demonstrated to be controlled by vacancy-solute binding energies out to fourth-nearest neighbor distances utilizing vacancy-mediated lattice kinetics Monte Carlo (LKMC) simulations. See the following short review articles for some details:

• Lattice kinetic Monte Carlo (LKMC) simulations, where diffusion is mediated by a monovacancy mechanism, of the temporal kinetics of the evolution of the nano- and microstructures of Ni-Al-Cr alloys, with detailed comparisons to the experimental data acquired employing atom-probe tomography, permits us to explain the detailed kinetic trajectories and the morphological evolution of nanometer size gamma-prime precipitates. We have recently (2017) implemented the use of two mono-vacancies in the simulation cell, which permits us to extend the simulated aging time to 400 hours, thus resulting in more detailed comparisons with the experimental atom-probe tomographic results: this was accomplished in cooperation with Dr. Enrique Martinez, Los Alamos National Laboratory. Additionally, we are presently developing pair-wise interatomic potentials, to fourth nearest-neighbors, for the Ni-Al-Mo system and to perform vacancy-mediated LKMC simulations of the temporal evolution of the nanostructure. The interaction terms in the pair-wise interatomic potentials are determined from first-principles calculations using the Vienna ab initio simulation program (VASP). This research also requires the calculation of the Ni-Al-Mo phase diagram using Grand Canonical Monte Carlo simulations and parameterizing the kinetics for this system.

• Turbine blades in commercial and military jet engines and land-based natural gas turbines are fabricated from nickel-based superalloys and are two-phase single-crystal alloys containing as many as 10 elements. The turbine blades are produced by a highly sophisticated casting process that often results in so-called “freckles,” which are produced in the mushy zone during the solidification process and are defects that need to be eliminated to improve the performance of jet engines. “Freckles” appear on the surfaces of turbine blades and are deleterious to their high-temperature performance. Toward understanding the mechanism(s) of the formation of freckles in the mushy zone, which appear during solidification processing we studied the crystallography and chemistry of “freckles” at all length scales, from the sub-nanometer to millimeter using a wide range of experimental techniques: optical microscopy, scanning electron microscopy, transmission electron microscopy, electron-back scattering diffraction patterns in conjunction with a dual-beam focused-ion beam microscope, and atom-probe tomography.

• Temporal evolution of the nanostructures of Al-Zr and Al-Zr-Ti base alloys and their

relationships to high-temperature creep properties (0.6 to 0.7 of the absolute melting point of aluminum) are investigated in detail in cooperation with Prof. D. C. Dunand since 1998. This research is aimed at the development of an aluminum alloy for use at higher temperatures than all existing aluminum alloys. We have learned a great deal about the nucleation, growth and coarsening of precipitates in systems that involve a peritectic reaction as opposed to a eutectic reaction; the latter is much simpler. This research involves the use of the following characterization tools: APT, TEM, SEM, optical microscopy, secondary ion mass-spectroscopy (SIMS), microhardness and AC electrical conductivity.

Temporal evolution of the nanostructures of Al(Sc,X,) alloys, where X = Mg, Zr, Ti, and/or X = rare earth (RE) elements, or Li, and the relationships of the nanostructures to high temperature creep properties (0.6 to 0.7 of the absolute melting point of aluminum). This research is also dedicated to the development of an aluminum alloy for use at higher temperatures than all existing aluminum alloys; that is, greater than 0.6 of the absolute melting point of Al. We have learned and are learning a great deal about the nucleation, growth, and coarsening of Al3(Sc1-xXx) precipitates in these relatively simple alloys, where the decomposition of the alloy is also a first-order phase transformation. The experimental tools are atom-probe tomography, transmission electron microscopy, high resolution electron microscopy, scanning electron microscopy, microhardness measurements, AC electrical conductivity measurements, and creep measurements (in cooperation with Prof. D. C. Dunand). See the articles below concerning the search for a castable high-temperature creep resistant Al-based alloy, which can be commercialized.

Initially, Al-Sc-based alloys,3 were studied because of all the metallic elements in the

periodic table that are soluble in aluminum Sc (Z = 21) results in the highest increment of

strength per Sc atom.4,5 The reason for this is that aging a Sc-supersaturated Al-Sc alloy at, for example, 300 oC (~0.6 of the absolute melting point of Al, Tmp), in the two-phase ��Al plus Al3Sc(L12-structure) phase-field, one obtains a high number-density of Al3Sc(L12-structure) nanoprecipitates, with small edge-to-edge distances between them, which results in Orowan strengthening, that is, dislocation looping. The Al3Sc nanoprecipitates have a melting point of approximately 1300 oC and hence they do not readily dissolve at 300 oC as is the case for precipitates in commercial Al-Cu-based alloys, which have the highest usable operating temperatures, ~225 to ~250 oC (~0.53 to ~0.56 Tmp).

The next key step in this research was the addition of zirconium to Al-Sc alloys; Zr has a

significantly smaller diffusivity than does Sc and it forms a Zr-rich shell around an Al3Sc-core, albeit with some substitution of Zr on the Sc-sublattice of Al3Sc, yielding Al3(Sc1-xZrx) core-shell precipitates as demonstrated utilizing atom-probe tomography (APT).6,7 It is noted that all of the Al-Sc based alloys are microalloys with ~1000 plus atomic parts per million of solute atoms. These Al3(Sc1-xZrx) core-shell nanoprecipitates coarsen slower at 375 oC (~0.7 Tmp) than do the Al3Sc nanoprecipitates, thereby demonstrating the importance of the chemically and structurally tailored Al3(Sc1-xZrx) nanoprecipitates in determining the coarsening kinetics. The basic building block of this new class of Al-superalloys are Al3(Sc1-xZrx) nanoprecipitates, which were further chemically and structurally tailored to decrease the Sc concentration8,9 and to increase their strength and high-temperature creep resistance10. Additionally, the elements from groups VB (V, Nb, Ta) and VIB (Cr, Mo, W) are being utilized; for example, vanadium was incorporated into Al-Er-Sc-Zr-Si alloys 11

The basic scientific research, which utilizes the principles of physical metallurgy, lead to the development of a new class of aluminum superalloys as described briefly above.

The Ford-Northwestern-Boeing Alliance, commenced 2005, and the Ford-Northwestern

Alliance permitted further development and improvement of aluminum superalloys for two main industrial topics: (1) the replacement of titanium brackets that hold auxiliary power motors in place in the rear of Boeing’s airplanes with an aluminum superalloy, with an emphasis on weldability; and (2) the replacement of front-end cast-iron brake-rotors in automotive vehicles, for example, Ford Focus and Ford Fusion, with an aluminum-alloy brake-rotor; this is an Al alloy developed by NanoAl LLC, Skokie, IL 60077, for commercial use by Ford Motors. Boeing wanted an aluminum superalloy with an additional metric to the one required by Ford Motors, specifically friction-stir weldability. The aluminum alloy for Boeing, to replace titanium, is Al-Mg-Sc and its weldability was demonstrated.12

Seidman’s contribution has been to develop a series of microalloyed aluminum alloys that have higher temperature capabilities. These alloys have been able to extend the operating temperature of aluminum from approximately 250 to 425 oC. This temperature range opens up potential applications for these microalloyed aluminum alloys to include components such as brake rotor substrates and pistons. Thus, he has been able to translate successfully fundamental research utilizing basic physical metallurgy concepts concerning strengthening mechanisms in these microalloyed aluminum alloys into alloys with a practical implementation path. This has been recognized by the awarding of US Patent No. 9,551,050B2; patents for new aluminum alloys are not easily granted, and this patent is a recognition of the new and unique technology his research was able to create.

and toughness as measured by the Charpy impact values: this research was initially performed in cooperation with the late Prof. Emeritus M. E. Fine, who passed away in 2015 at the age of 97. A deep understanding of the nucleation, growth, and coarsening behavior of concentrated multicomponent alloys of technological value was obtained from these studies. These alloys were characterized using APT, TEM, SEM, optical microscopy, microhardness measurements, tensile and Charpy impact tests. Additionally, the chemistry of the copper-rich precipitates were form were studied using first-principles calculations employing VASP and the results were compared with the experimental observations obtained using atom-probe tomography. Additionally, we studied fusion welding of these iron-copper based alloys, which demonstrated that they are readily welded, which is another metric specified by the Navy.

• Additionally, a thermally stable Ni-rich austenite formed utilizing a Quench-Lamellarization-Tempering (QLT) treatment for a 10 wt. % Ni martensitic steel contributes to its superior mechanical properties, specifically ballistic resistance. We analyzed the thermodynamic stability of inter-critically formed austenite and the kinetics of its formation during the QLT-treatment. Dilatometry demonstrated that the austenite formed during the L-step at 650 oC begins to transform to martensite during the quenching treatment (following the L-step), with the transformation commencing at 188 oC. Austenite formed after the T-step tempering treatment at 590oC, is, however, thermally stable even at sub-ambient temperatures, as revealed by synchrotron X-ray diffraction. 3-D ultraviolet (wavelength – 355 nm) laser assisted atom-probe tomography (APT) indicated that nanolayers of austenite grow during the T-step with a higher Ni concentration (22 at. %) on the retained austenite from the L-step containing a lower Ni concentration (14.5-17 at. %). DICTRA simulations demonstrated that the austenite growth during the T-step occurs predominantly in the Ni-rich fresh-martensitic regions, which form during quenching following the L-step. These Ni-rich regions enhance the growth kinetics of austenite during the T-step, resulting in an increase in its volume-fraction from 8.1 to 18.5 %, after 1 h of tempering at 590oC. The Ghosh-Olson thermodynamic and kinetic approach was used to predict the sub-ambient martensite-start temperature of the Ni-rich QLT-processed austenite, which cannot be predicted by empirical relationships.

______________________________________________________________________________ • The key technology for the linear collider is the high gradient superconducting radio-frequency

(SRF) cavity, approximately 20,000 of which will make up the accelerator. The preferred technology was initially to fabricate the cavities from high-purity niobium sheet. From the RF superconductivity point-of-view, the interface between the native niobium oxide on the surface of the cavity and near sub-surface region is the most important one. Superconducting properties of cavities depend on the chemistry and microstructure of the surface oxide and the concentration and location of impurity elements. Little was known, however, about this and the effects of low-temperature baking on the surface region. We employed APT to analyze this near surface region with a particular emphasis on the stoichiometries of the niobium oxides that form and the hydrogen concentration profiles that exist in the niobium oxides and bulk niobium. Specifically, we performed correlative atom-probe tomography and aberration-corrected STEM/EELS to study hydrogen, hydrides and oxides in ‘pure niobium.

• We are currently studying (started fall 2016) Nb3Sn layers (2 to 4 microns thick) on Nb cavities, with 3 mm thick walls, to understand how they will improve the behavior of the superconducting radio frequency cavities operating at 2.2 K. This research is being performed in cooperation with researchers at the technical division of Fermi National Accelerator Laboratory (FNAL).

______________________________________________________________________________ • The fundamental aim of this research was to utilize local-electrode atom-probe (LEAP)

tomography to study the three-dimensional atomic-level structure of magnetic multilayers. Previous research indicated that the transport and magnetic properties of magnetic tunnel junction (MTJ) structures, which are used as memory storage devices and magnetic field sensors, depend strongly upon the character of the multilayer’s interfaces. LEAP tomography is ideal for characterizing the morphology and compositional character of the multilayer structure and interfaces at a sub-nanometer scale.

• Much progress was made on this research topic. Collaborations were established with several groups (Seagate Technology, Canon-ANELVA Corporation and NIST-Maryland) to grow high quality thin-film samples. Procedures were developed for the production of atom probe specimens from thin films grown on silicon wafers using the dual-beam FIB microscope at Argonne National Laboratory, and these specimens have been successfully analyzed in the LEAP tomograph. Interestingly, we find that the tunnel barriers in these first simple MTJs (CoFe/MgO/CoFe) were chemically asymmetric; the lower CoFe layer is found to be slightly oxidized at the CoFe/MgO interface as a result of the growth technique. Additionally, the tunneling I-V character of these structures is asymmetric as a result of this chemical asymmetry. After annealing the structure at 340 °C for 1 h the chemical and I-V asymmetry are both reduced, highlighting the direct connection between very fine scale microstructure and transport behavior.

• Segregation of impurity (unintentional) or solute (intentional) atoms at either grain boundaries

or heterophase interfaces affects the mechanical and electrical properties of materials, which is a ubiquitous phenomenon is in all materials. I have had a strong research program in this area studying grain boundaries in metallic alloys and metal/ceramic heterophase interfaces, with a strong experimental emphasis on studying segregation at the atomic scale (subnanometer) employing atom-probe field-ion microscopy (APFIM), atom-probe tomography and transmission electron microscopy.

• Additionally, Metropolis algorithm Monte Carlo simulations are performed to study segregation of solute atoms in binary metallic alloys on an atomic scale as a function of a grain boundary’s five macroscopic and three microscopic degrees of freedom. The combination of atomic scale experimental observations and Monte Carlo simulations resulted in a significantly deeper understanding of segregation at grain boundaries than existed prior to when this research program commenced.

• In 2007 an article by Sato et al. at Tohoku University, published in the journal Science, presented results on the ternary alloy Co-Al-W with a gamma(f.c.c.) plus gamma-prime(L12 structure) phase-field and a tiny gamma-prime(L12 structure) phase-field, which exhibited a two-phase microstructure consisting of gamma-prime precipitates (L12 structure) in a gamma (f.c.c.) matrix. Stress-strain diagrams, as a function of temperature, exhibited an anomalous increase in yield stress with increasing stress. Hence, these initial results for Co-Al-W alloys are analogous to what exists in Ni-Al-Cr alloys, which are the best high-temperature superalloys in existence, with many important practical applications for the aviation and electricity generating industries. The Sato et al. article caused many additional research groups around the world to commence working on Co-Al-W alloys: USA, Germany, Japan, China, England, India, General Electric Global Research in Niskayuna, New York, and NIST, Gaithersburg, Maryland.

• The hope for Co-based superalloys is that they have the potential to supplant Ni-based superalloys for use as turbine blades and disks in jet engines and also in land-based natural gas fired turbine engines employed for generating electricity. The increase of the maximum operating temperature of nickel-based superalloys is approaching a constant. If the maximum operating temperature of cobalt-based superalloys can be made to exceed that of nickel-based superalloys then the energies of many researchers around the world will have paid off. It is too soon to tell if this possibility will become a reality.

• It was quickly demonstrated experimentally that the Co3-x- y(AlxWy)-precipitate-phase is metastable with increasing temperature and that significant Ni additions are required to increase the dimensions of the gamma(f.c.c.) plus gamma-prime(L12 structure) phase-field. Additionally, other elements had to be added to the Co-Al-W alloy to obtain elevated liquidus, solidus and solvus temperatures. Specifically, Co-Al-W-Ti-Ta-B alloys were demonstrated to be necessary. Boron was added to strengthen the grain boundaries in polycrystalline specimens. Research at Northwestern University was initiated by D. N. Seidman and D. C. Dunand in cooperation with R. D. Noebe and C. K. Sudbrack at NASA Glenn Research, Cleveland, Ohio and later with E. Lass, C. Campbell and U. Kattner at NIST, Gaithersburn, Maryland. And more recently J.

Scientific Accomplishments, 1965 to the present

New York University, 1960-1962

• For my M.S. thesis research I determined the degree of non-stoichiometry of the semiconductor PbSe, which was thought to be a line compound in the then extant Pb-Se phase diagram. The motivation for these experiments is that PbSe exhibits a reasonable thermoelectric power and hence was thought to be a suitable candidate for small refrigeration systems in remote areas that are not hooked up to an electrical grid system. To determine the degree of nonstoichiometry I grew single crystals of PbxSey with values of x and y that differed from unity, thereby creating p-n junctions in the crystals at different positions. From the locations of the p-n junctions in the single crystals I was able to calculate the range of stability of PbSe over a reasonable temperature range. Additionally, I redetermined a portion of the Pb-Se phase diagram and showed that a then recently postulated monotectic reaction did not exist. Ironically, I returned to the subject of bulk thermoelectric materials as a result of an Energy Frontier Research Center (EFRC) on this subject at Northwestern University many years later.

• For my Ph.D. thesis research, at the University of Illinois at Urbana-Champaign, I demonstrated that dislocations are the dominant sources of vacancies in a polycrystalline metal, which was accomplished by performing up-quenching experiments on gold and measuring the kinetics of vacancy production in the millisecond range; my Ph.D. thesis supervisor was Robert W. Balluffi, who is alive and well at age 93. These experiments also demonstrated that the efficiency of dislocation climb is a function of the vacancy subsaturation; that is, the chemical potential of a vacancy determines the climb velocity, that is, the kinetics of vacancy producdtion. Additionally, these experiments settled a controversy, precipitated by a theory of the late Prof. Doris Kuhlmann-Wilsdorf (University of Virginia), which asserted that “old” dislocations cannot climb.

• As a postdoctoral student, at Cornell University, I set-up a laboratory to study the kinetics

of vacancy decay at elevated temperatures by quenching from one elevated temperature to a lower elevated temperature without quenching to room temperature, which constituted a completely new approach to this problem. This was accomplished with fully automated electronic equipment, which circumvented problems associated with quenching to room temperature and provided a deeper understanding into the efficiency of dislocation climb as a function of the vacancy supersaturation in gold; the kinetics of vacancy decay at the lower elevated temperature were followed at temperature using resistivity measurements. Between the up-quenching experiments and these down-quenching experiments it was found that there is fundamental asymmetry in how dislocations climb in the presence of sub- and super-saturations of vacancies, which had not been understood and was clarified. Based on these experimental results a correlation was found between the chemical potential of a vacancy and the efficiency of dislocation climb; that is, the velocity of climb for the experimental conditions compared to diffusion-limited climb, which is the fastest possible climb velocity.

quantitatively the fundamental properties of point defects in quenched or irradiated metals employing an ultrahigh vacuum field-ion microscope (FIM); I became an assistant professor in January 1966. Ultrahigh vacuum (UHV) FIMs were designed and fabricated, as well as liquid-helium cryostats, which permitted FIM specimens to be cooled to temperatures as low as 10 K. Two UHV FIMs were attached to a low-energy (60 kV for singly-charged ions) heavy-metal ion accelerator, with magnetic mass analyses of the ion beam, utilizing three differential stages of pumping, which allowed FIM specimens to be irradiated in situ under UHV conditions at temperatures as low as 10 K.

• Firstly, using an UHV-FIM, the direct observations of individual mono- and divacancies were made in quenched platinum specimens, thereby yielding the first direct experimental measurement of the ratio of mono- to divacancy concentrations, which yielded an absolute value of the binding free energy of a divacancy that was model independent. This result permitted a detailed explanation of diffusion in platinum to be made in terms of the mono- and divacancy concentrations, without adjustable fitting parameters. The experiments also yielded an absolute value for the specific resistivity of a vacancy in platinum.

• I developed an extensive program to study experimentally the character of displacement cascades produced by single heavy metal-ions, which were studied in detail using the above described system for irradiating in situ metal FIM specimens. This research yielded the distributions of vacancies within displacement cascades as revealed by radial distribution functions (RDFs) and demonstrated how the RDFs change systematically with the mass of an incident ion at constant incident energy; the studies were performed on both tungsten and platinum specimens. The experimental results also demonstrated that the self-interstitials created within displacement cascades were transported away via focused

replacement collision sequences. The result of this program of research was a detailed insight into the primary state of radiation damage in the absence of thermal migration of the point defects created.

• To accomplish this required the development of what is currently called three-dimensional (3-D) field-ion microscopy, which involved dissecting a field-ion microscope specimen in a highly controlled manner on an atom-by-atom basis and an atomic-plane by atomic-plane basis. In between each field-evaporation pulse an FIM image was recorded on 35 mm cine film, which had a 1000-foot cartridge. Each 1000 feet of 35 mm cine film was analyzed using a two-dimensional analysis instrument that permitted us to record the positions of every atom in a given {hkl} plane and then using software to reconstruct a 3-D map of atoms, vacancies and self-interstitial atoms. All of the above was reported in an unpublished Cornell University Materials Science Report #1159 by R. M. Scanlan et al., 1969. Recently a modern version of what we had performed in 1969 has been accomplished using a charge coupled device (CCD) camera by researchers at the University of Rouen and the University of Oxford, F. Vurpillot et al., (2017).

• Additionally, the elastically deposited energy, from a large number of implanted ions, was determined as a function of depth by measuring the profile of the vacancy damage created in platinum specimens. This was the first direct experimental determination of the elastically deposited energy and perhaps the only one to date. Physically the elastically deposited energy is the energy expended in creating point defects and by definition requires detection of all the vacancies and self-interstitial atoms (SIAs). This is a unique approach to determine this basic physical quantity, associated with radiation damage, because it has atomic scale resolution.

• The diffusivities of self-interstitial atoms in W, Pt, Pt-Au, Mo, Mo-Re, ordered Ni4Mo, and

ordered Pt3Co were directly determined from in situ irradiation experiments using the apparatus described above. For these experiments specimens were irradiated at 10 K, which is below the temperature where self-interstitial atoms (SIAs) migrate in these metals. The FIM specimens were then warmed continuously from 10 K, with the surface of the

specimens serving as a strong sink for SIAs; this experiment is essentially an isochronal warming experiment. The SIAs were detected by the contrast effects they produced when they arrived at the free surface, and the temperature at which they migrated freely was detected by a peak in the flux of SIAs arriving at the free surface. A mathematical diffusion model was developed to extract the diffusivities and migration energies of the migrating SIAs. Additionally, the experiments yielded the volume change of migration of a SIA, since an FIM specimen is subjected, to first order, to a negative hydrostatic pressure. Similar experiments performed on specimens of the alloys Pt-Au and Mo-Re provided direct evidence for the trapping of SIAs at solute atoms. Additionally, experiments on the ordered alloys Ni4Mo and Pt3Co yielded direct evidence for two different geometric forms of the SIAs in these ordered compounds.

• The ordered alloys Ni4Mo and Pt3Co were used to study directly and quantitatively elastically deposited energy profiles. This was accomplished by measuring the change in the Bragg-Williams long-range order (LRO) parameter as a function of depth from the irradiated surface of a FIM nanotip. The classical definition of the LRO could be used directly because of changes in the contrast of the FIM patterns on an atomic scale. Additionally, the elastically deposited energy profiles were determined as a function of both ion energy and crystallographic <hkl> direction. These results yielded one of the only experimental checks of ion-solid scattering theories at low energies, and also provided direct evidence for channeling of the implanted ions at low energies; that is, less than 1500 Vdc.

• To understand the basic physics of field-ion microscopy I initiated a series of experiments

on the process of field-ionization, which involves the quantum mechanical tunneling of an imaging gas atom’s outermost electron into an FIM specimen. This involved fabricating a miniature Faraday cup, compatible with UHV, to detect the helium ion-current from individual {hkl} atomic planes as a function of the applied electric field; Wei and Seidman, 1977. This experiment demonstrated that the probability of ionization of an atom residing in a given {hkl} plane was a strong function of both its {hkl} crystallography and local electric field. Thereby, providing a physical explanation for the so-called current-voltage characteristic curves of an entire nanotip.

• Additionally, the temperature dependence of the resolution of a field-ion microscope was determined by measuring the image diameter of an atom as function of a nanotip’s temperature at constant electric field. The results of this experiment showed unequivocally that the field-ionized helium atoms have a quadratic dependence on the temperature of a nanotip, which is a direct reflection of the fact that they are thermally accommodated to a certain degree. The experiments demonstrated, however, that helium atoms are not fully accommodated to the temperature of the nanotip at the moment they are field-ionized.

• After the invention of the atom-probe field-ion microscope (APFIM) by Mueller, Panitz and McLane, in 1968, I commenced building an ultrahigh vacuum APFIM, which was controlled completely by a computer; that is, the process of initiating field-evaporation pulses and the detection of the field-evaporated ions employing a micro-channel plate occurred without human intervention. The detection process yields the time-of-flight and therefore the mass-to-charge state ratio of an ion, that is, its chemical identity. This was accomplished using a Data General Nova 6 computer, which was one of the early commercial computers for controlling scientific equipment in a laboratory. This APFIM also had a specimen exchange device, a double-tilt goniometer stage, and a low-energy ion gun attached to it, with magnetic mass filtering of the ion-beam: Amano and Seidman, 1979. The appearance of an article, 1977, on this APFIM at Cornell University set the platinum standard for all future APFIMs fabricated around the world.

• I emphasize strongly that when this UHV APFIM was fabricated it was not possible to purchase a UHV compatible double-tilt goniometer stage, a specimen exchange device, a low-energy ion gun with magnetic mass filtering, and hence they were all fabricated in the Instrument Shop of the Laboratory of Atomic and Solid State Physics (LASSP) at Cornell University. Additionally, a commercial time-to-digital converter with a resolution of better than 10 nsec was not commercially available and one had to be fabricated, which was made

possible with advice from the Newman Laboratory’s electronics shop; the latter served the experimental particle physicists at Cornell.

• In my first archival article describing the UHV APFIM in detail, results were also presented for tungsten, molybdenum, a molybdenum-titanium alloy, a molybdenum-titanium-zirconium (TZM) alloy, a low swelling stainless steel (L1A), and an iron-based metallic glass (Metglass 2826). The results obtained demonstrated the power of an APFIM for extracting chemical information on an atomic scale and indicated that a wide range of materials could be readily studied.

• The UHV APFIM was employed to study the fundamental properties of 4He and 3He in tungsten, where the 4He or 3He atoms were implanted using an attached low-energy ion gun with magnetic mas- filtering; the latter was separated from the APFIM by a single stage of differential pumping, which was important for maintaining UHV conditions in the APFIM during the helium implantation process. The motivation for this experiment was the fact that helium is a by-product of so-called no-a reactions in neutron (no) irradiated materials; when a-particles come to rest in a lattice they are helium atoms. At the time of our experiments simulations of the diffusion of helium in f.c.c. and b.c.c. metals indicated an activation energy for diffusion of ~0.25±0.25 eV, whereas thermal desorption experiments indicated that the same activation energy is several electron volts. Since

helium is insoluble in all metals it precipitates out and resides in bubbles, which are deleterious to nuclear reactor materials. To model the behavior of reactor materials in the presence of helium bubbles it is essential to know the diffusivity of helium atoms and this experiment was specificanlly designed to measure this quantity.

• The experiments were performed by implanting 4He or 3He into perfect tungsten specimens, at a cryogenic temperature, 10 K, using an implantation energy of 300 eV, which transferred energy to a primary knock-on atom of tungsten, which was well below the threshhold energy for producing stable Frenkel pairs; therefore at 300 eV the production of Frenkel pairs was completely suppressed. Then the immobile implantation profile was determined by APFIM in situ at the implantation temperature, which served as a reference state. The implanted specimen was then aged isothermally at a series of elevated temperatures for fixed periods of time, and the implantation profiles were re-measured after each aging treatment. The temperature and time dependence of the recovery of the implanted 4He or 3He profile yielded the diffusivity and migration energy of interstitial helium for 4He or 3He and the activation energy for migration, which was determined to be 0.24±0.10 eV for both isotopes, with no measurable classical isotope effect in the pre-exponential factor of the diffusivity. The reason for the discrepancy between the model calculations and the thermal desorption experiments is that the experiments utilized an implantation energy that created stable Frenkel pairs, and the implanted helium atoms wound up being trapped at vacancies with a large binding energy. Hence, the desorption experiments measured the sum of the binding and migration energies of helium and not simply a migration energy, whereas the APFIM experiments utilized an implantation energy that did not produce deep point defect traps for helium. Our studies constitute the only experimental studies of implanted helium atoms in the complete absence of radiation damage. We also utilized the APFIM to study hydrogen implanted in tungsten at 29 K.

• An alloy subjected to fast neutron irradiation has a dynamic phase diagram with the flux of neutrons, number of neutrons per unit area per unit time, being the control variable. Irradiation of a specimen is an example of a driven system as it is an open thermodynamic system and one does not know a priori what the final state of the system will look like This dynamic phase diagram is determined by the kinetic properties of the point defects produced, vacancies and self-interstitial atoms (SIAs) and their interactions with the solvent and solute atoms constituting the alloy. It is theoretically possible to obtain either homogeneous radiation-induced precipitation (RIP) or heterogeneous RIP at pre-existing lattice defects in a specimen (G. Martin and P. Bellon). To study these ideas experimentally on an atomic scale W-10 at.% Re and W-25% Re specimens were fast-neutron irradiated in EBR-II and subsequently studied by APFIM; both Re concentrations were such that at the irradiation temperature the alloys were in the primary single-phase field of the W-Re phase diagram. After irradiation both alloys contained precipitates and by measuring their compositions it was demonstrated that the precipitates were homogeneously nucleated, thereby validating the idea that homogeneous RIP is possible. Possible kinetic pathways were for the precipitation processes were suggested.

• Next my interests turned toward interfacial segregation phenomena and the system chosen for the initial studies were Co-Nb and Co-Fe alloys, because the free energy difference between the f.c.c. and h.c.p. phases of these cobalt-base alloys is very small and therefore the alloys contain a high number density of intrinsic stacking faults. The stacking faults served as simple and well-defined two dimensional planar interfaces for segregants. The temperature dependence of segregation at stacking faults in Co-Nb and Co-Fe alloys was studied by APFIM and the enthalpy of segregation of Nb or Fe to stacking faults was measured in Co-Nb and Co-Fe alloys. A classical thermodynamic model was developed for interfacial segregation at stacking faults was developed, which took into account solute-solute interactions within the plane of the stacking fault. These experiments and analyses developed constituted the first quantitative study of segregation at stacking faults by APFIM, and they served as a basis for the segregation studies I performed at Northwestern University.

• Additionally, studies were made of the APFIM’s ability, as an instrument, for studying order-disorder phenomena in Ni4Mo and Pt3Co, and as a result analysis techniques were developed for performing quantitative experiments with this technique.

• At Northwestern University I continued initially an effort in the area of radiation damage,

which involved a search for the amorphization of silicon using high-energy electrons (1 MeV) in the Argonne National Laboratory high-energy electron microscope. The first result was negative as no matter how low the temperature of the silicon specimen, 6 K, it could not be amorphized using electrons. A byproduct of this research was, however, the discovery that simultaneous irradiation with 1 MeV electrons and heavy ions could result in either amorphization or the suppression of amorphization, which was both a novel and surprising result that was explainable in terms of the production of Frenkel pairs by electron irradiation and displacement cascades by heavy ions.

• After arriving at Northwestern, September 1st, 1985, I decided to focus on the problem of interfacial segregation because of its importance in so many phenomena in materials science and engineering. Initially, I concentrated on grain-boundary segregation in binary metallic alloys because dealing with single-phase materials reduces the level of complexity somewhat, although in hindsight not radically. A grain boundary is characterized by five macroscopic degrees of freedom (DOF) and three microscopic DOF. The experimental approach involved measuring the five macroscopic DOF by transmission electron microscopy and the Gibbsian interfacial excess of solute using atom-probe field-ion microscopy (APFIM), which necessitated modifying a double-tilt holder for a transmission electron microscope to hold APFIM specimens. A procedure was developed that permitted us to find a grain boundary in an APFIM specimen, determine its five DOF, then back polish the specimen using a specially fabricated millisecond electropolishing unit to bring the grain boundary close to a nanotip’s surface in an APFIM specimen. Then the specimen was transferred to the APFIM to analyze chemically the grain boundary. This experimental procedure was a tour de force, which enabled us to obtain information that had heretofore not been obtained by any other technique.

• The physical quantity measured by the atom-probe FIM for a grain-boundary (GB) is the Gibbsian interfacial excess of solute, which is the correct thermodynamic quantity to determine the level of segregation without any assumptions as to how the excess solute atoms are arranged at a GB. I was the first one to realize that it is possible to extract the Gibbsian interfacial excess utilizing an APFIM. This approach was applied to grain boundaries in Mo-Re, Pt-Ni, and Fe-Si alloys. In the case of the Fe-Si alloy sufficient data was collected to sample a significant portion of grain-boundary space for segregation. Specifically, the Gibbsian interfacial excess of solute was plotted as a function of the sin(q/2), where q is the rotation angle about the disorientation vector, c, and the dot product of the c and n vectors; the n vector is the unit normal to the grain boundary plane; when this dot product is zero c is parallel to n and the grain boundaries are symmetric twist boundaries, when this dot product is unity the grain boundaries are symmetric tilt boundaries. For values of this dot product other than zero and unity the grain boundaries are nonsymmetrical and are neither pure tilt of pure twist in character. For the experimental data obtained this plot yields a surface of the Gibbsian interfacial excess of solute as a function of the five macroscopic DOF, where the five macroscopic DOF have been folded into two axes. Plotting the experimental data in this manner yields physical insight into the absorptive capacity of different types of grain boundaries for solute atoms, which is not, once again, obtainable by any other technique.

• In parallel with the experimental program on grain boundary segregation I started an effort at modeling GB segregation using initially linear isotropic elasticity theory to look at the interaction of a solitary solute atom with a tilt boundary or a twist boundary. The elastic interactions were the classical first and second-order interactions (pDV and elastic moduli effects), which yielded some insights, all within a continuum framework, which I found to be less than satisfying. Hence, I switched to performing Monte Carlo simulations



(Past and Present),

52

using embedded atom method (EAM) potentials, which had been developed by M. I. Baskes, M. Daw and S. Foiles (Sandia Laboratories, Livermore, CA) and are continuous long-range potentials. The well-known Metropolis algorithm was employed and in addition to switching the chemical identities of atoms we also included random relaxations of atoms in the unit cell, which is important because solute atoms can be either oversize or undersize with respect to the matrix atoms. The Monte Carlo simulations were performed for both symmetric twist and tilt boundaries, which were studied both without and with solute atoms to make certain that the anticipated grain boundary structures we obtained agreed with those of well- known boundaries, which had been studied experimentally employing high resolution electron microscopy. The systems studied were Au-Pt, Ni-Pt, and Ni-Pd.

• The first Monte Carlo simulations were performed for symmetric [001] twist boundaries in Pt-Au, which showed that the Au solute atoms are segregated at grain boundaries with unique patterns, which were not predicted using linear isotropic elasticity theory and therefore showed clearly the limitations of this classical continuum approach. These detailed Monte Carlo simulations were also used to determine the temperature dependence of segregation, which yielded both the enthalpy and entropy of segregation for symmetric [001] twist boundaries in a Pt-Au alloy. The results demonstrated that the value of the Gibbsian interfacial excess of Au increased with increasing twist angle and then reached a level plateau in the high-angle regime.

• It was discovered utilizing Monte Carlo simulations that the microscopic DOF can affect

strongly the value of the Gibbsian interfacial excess of solute. That is, a grain boundary with a specified set of macroscopic DOF but with different sets of microscopic DOF can have significantly different values of the Gibbsian interfacial excess of solute. This result is important because it explains why Auger spectroscopy often yields very different levels of segregation for the same grain boundaries.

• Monte Carlo simulations were then used to study in great depth Gibbsian segregation at a

series of [110] symmetric tilt boundaries in a Ni-Pd alloy; this alloy was chosen because it exhibits a continuous series of solid-solutions at the temperature chosen for the segregation studies. A first step in this research involved studying grain boundaries in pristine nickel to determine the lowest energy structure(s) for each tilt angle. This involved first using molecular statics simulation at 0 K to find the lowest energy structure(s), which lead to the surprising result that for a given tilt angle there are often geometrically different structures that have identical energies. Hence, the bicrystals were annealed at the segregation temperature using a Monte Carlo (Metropolis algorithm) code, which resulted



(Past and Present),

53

in a smaller number of stable of grain boundary structures for each tilt angle. After analyzing the structural units in the stable grain boundary structures it was concluded that the popular structural unit model (SUM) for describing grain boundaries has no predictive power whatsoever, much to the chagrin of its proponent.

• The next step in this research program was to study segregation of Pd at the grain boundary structures found to be stable at the segregation temperature. The overlapping distributions Monte Carlo technique was employed to calculate segregation free energy distributions of the solute, Pd, at all the tilt boundaries. Firstly, it was found that tilt boundaries contain both attractive and repulsive sites for Pd. Secondly, the segregation free energy distributions were classified into three general types of distributions: (a) segregation occurs mainly at sites associated within the cores of the grain boundary dislocations; (b) segregation occurs at a combination of core and elastically strained sites; and (c) segregation occurs primarily at elastically strained sites. This detailed physical picture of segregation at grain boundaries is significantly different from one found in text books and review articles on this subject.

• A major result of all the research on grain boundaries is the proof that the five macroscopic

degrees of freedom are thermodynamic state variables, as postulated by the late John W. Cahn. That is, the Gibbsian interfacial excess of solute at a grain boundary is a function of the five macroscopic degrees of freedom and therefore a five-dimensional space for grain-boundary segregation exists, implying that the local phase rule for interfaces postulated by J. W. Cahn is correct; that is, the Gibbs phase rule for bulk phases needs to modified to take into account the five DOFs when applied to grain-boundaries, such that it becomes f + f = C + 7, where f is the number of phases at a grain boundary, f is the number of degrees of freedom, C is the number of components in the system, and 7 stands for pressure, temperature, and the five macroscopic DOF.

• By using the displacement shift complete (DSC) lattice we demonstrated the effects of the

three microscopic degrees of freedom (DOF) on Gibbsian segregation at a series of [110] symmetric tilt grain-boundaries (STGBs). Specifically, for a given STGB with fixed macroscopic DOF but different microscopic DOF the values of the Gibbsian excess of solute were shown to depend on the microscopic DOF. This result was unanticipated and met with some skepticism at the time, which has since disappeared.

• Low-density TiAl alloys are of potential value for use at high temperatures in both jet engines and land-based gas turbine engines, as a possible replacement for the more dense nickel-based alloys, in the cooler portions of an engine. We studied with conventional atom-probe tomography a series of TiAl alloys, with a-2/g heterophase interfaces, that contained carbide precipitates, which are intentionally present to increase the high-

temperature creep resistance of these alloys. This research found that the oxygen that is present in TiAl alloys partitions to the carbide precipitates and hence the latter is an excellent getter for excess of oxygen, which embrittles TiAl alloys, thereby discovering a potential technique for reducing the brittle character of these alloys at lower temperatures.

• More recently I recommenced performing research on titanium alloys with Dr. James A. Coakley, a European Union Marie Curie Research Fellow, on precipitation in titanium alloys using both a LEAP4000X Si and a LEAP5000XS tomographs, with emphases place on the earliest stages of precipitation of the omega phase. The latter instrument, with a detection efficiency of 80% demonstrated that it is possible to detect the very earliest stages of precipitation of the omega-phase, which was not possible with the LEAP4000X Si.

• In series with the research program on segregation at grain boundaries and heterophase interfaces in metallic system I initiated a program on segregation at heterophase interfaces for ceramic/metal systems. This program had both experimental and simulational components; the latter involved first-principles calculations using density functional theory. The initial research was based on producing heterophase interfaces by internal oxidation of Cu-Mg and Ag-Cd alloys. For both systems this results in the formation of a high number density of nanometer scale octahedral-shaped MgO or CdO precipitates, which are faceted on {222} planes, which is a polar plane. The polar planes are either 100% cations or 100% anions: MgO is an excellent insulator with a large band gap energy,



(Past and Present),

57

whereas CdO is almost a semiconductor with a small band gap. Using atom-probe field-ion microscopy it was demonstrated that the terminating plane for the {222}MgO/Cu interface is the anion, oxygen, while for the {222}CdO/Ag heterophase interface it was found that the terminating plane may be either the cation, Ag, or the anion, O, with equal probabilities. Hence, the termination depends on the band gap of the metal oxide, which suggested that our results could be explained using first-principles calculations, which was indeed the case. The first-principles calculations demonstrated that for the {222}MgO/Cu heterophase interface that both cation (Mg-) and anion (O+) terminations are stable but an anion termination is more stable than a cation termination, which is in agreement with our experimental observations. For the {222}CdO/Ag heterophase interface both cation (Cd-) and anion (O+) terminations have the identical stability, from first principles calculations, to within many decimal places, which is also consistent with our atom-probe field-ion microscope experimental results.

• When the research on the {222}MgO/Cu heterophase interface commenced it was generally accepted, based on high-resolution electron-microscopy (HREM) observations, that this interface is incoherent because of the large misfit, ca. 15 %, between the Cu matrix and the MgO precipitates. Utilizing, however, a dedicated scanning transmission electron microscope (STEM) at Oak Ridge National Laboratory, with a point-to-point resolution of less than 0.2 nm, misfit dislocations were found with the correct inter-dislocation spacing, thereby proving that it is a semi-coherent interface. More generally it was demonstrated that answering the question as to the degree of coherency of an interface depends on the instrument used to detect the misfit dislocations.

• The electronic structure of the {222}MgO/Cu heterophase interface was studied utilizing

parallel electron energy-loss spectroscopy (EELS) measurements at Cornell University in a dedicated STEM; the EELS technique samples the unfilled electron energy levels; this work was performed in collaboration with D. A. Muller and J. Silcox. John Bardeen had postulated in the late 1940s the existence of metal-induced gap states (MIGS) for metal/semiconductor heterophase interfaces, which had not been observed at the time of our experiments for reasons that became transparent after we performed EELS experiments, which demonstrated that MIGS exists for the {222}MgO/Cu heterophase interface because MgO has a large band gap, 7.8 eV, implying that the interface states are highly localized and therefore detectable. Whereas for metal/silicon interfaces this is not the case (the band gap for silicon is only 1.11 eV) and hence they are not detectable using EELS. The experimental result for the {222}MgO/Cu heterophase interface is consistent with first-principles calculations we performed in parallel.

• Segregation of Ag at the {222}MgO/Cu heterophase interface was studied using atom-probe field-ion microscopy and the Gibbsian interfacial excess of Ag at this interface was determined, thereby determining this quantity for the first time in an unambiguous manner for a heterophase interface without extensive deconvolution. The reason for this is that internal oxidation produces heterophase interfaces that are free of impurity atoms and hence segregation can be studied of a specific solute atom without impurity atoms affecting its absorptive properties. Atom-probe field-ion microscopy was also used to study the segregation of Au at {222}CdO/Ag heterophase interfaces, thereby demonstrating the general applicability of this approach to another metal/metal-oxide internal interface.

• A similar experimental approach was used to study segregation of Sb at a-Fe/molybdenum

nitride interfaces, which were produced by internal nitridation of an a-Fe(Mo, Sb or Sn) alloy. The initial molybdenum nitride precipitates were platelets that were one or two atomic layers thick and had no misfit dislocations in spite of the large lattice parameter misfit, in excess of 20 %, between a-Fe and molybdenum nitride. In the absence of misfit dislocations the Gibbsian interfacial excess is very small, whereas as the molybdenum nitride platelets thicken the Gibbsian excess increases because of the appearance of misfit dislocations. Thereby, demonstrating that in this system the level of segregation is coupled with the presence of misfit dislocations and that the driving force may be the release of elastic strain energy associated with oversized Sb or Sn atoms, although one cannot rule out the role played by electronic effects without performing first-principles calculations. The presence of misfit dislocations was detected using HREM and it was shown that as the platelets thickened the number density of interfacial misfit dislocations increased but did not reach the requisite value to accommodate all of the elastic misfit strain energy, indicating that there was a problem nucleating dislocations.

• Our conventional atom-probe field-ion microscope was used to study interfacial segregation in a series of metal oxide/metal heterophase interfaces with the goal of finding rules for predicting which elements would segregate at a heterophase interface. The systems studied were MgO/Cu(Ag), MgO/Cu(Sb), CdO/Ag(Au) and MnO/Ag(Sb) and the Gibbsian interfacial excesses were measured for the different solute atoms, Ag, Sb, and Au. The so-called Wynblatt-Ku model, which is commonly used to predict whether or not an element segregates at an interface, was employed to see if it is in agreement with the observed experimental results and it was found that its “predictability” rating is ca. 50%, implying that is of limited value for metal oxide/metal systems. The reason for the failure of the Wynblatt-Ku model is that it neglects electronic effects and assumes that the main driving force for interfacial segregation is elastic; that is, the reduction in the misfit elastic strain energy associated with an oversize or undersize atom.

• In parallel with the experimental program on metal oxide/metal interfaces a first-

principles and simulational effort was executed. For example, the chemistry and bonding at {222} MgO/Cu heterophase interfaces was studied using first-principles calculations. Also, first principles simulations of a {222} MgO/Cu interface with misfit were performed thereby incorporating the dislocation structure of the interface for the first time for any ceramic/metal system. A classical interatomic potential for Nb-alumina interfaces was developed for studying structure-property relationships of oxide surfaces and interfaces. The effect of misfit on heterophase interface energies was studied in detail. Interface structure and energy calculations were performed for carbide precipitates in g-TiAl. And the partitioning of impurities in multi-phase TiAl alloys was theoretically studied.

• A major research effort, which is still ongoing, was undertaken to understand the detailed roles played by the major alloying elements in nickel-based superalloys used in both jet engines for military and commercial aircraft and land-based gas-turbine engines for generating electricity. This involved the preparation of a series of Ni-Al-Cr alloys, which are the basis of all commercial nickel-base alloys, and adding quaternary, quinary, and sexanary elements one at a time; the additional refractory alloying elements added are

tungsten, rhenium, tantalum, ruthenium, and niobium. Commercial nickel-base superalloys may contain upwards of eight to ten elements and each element has been added for a specific purpose. These excellent high-temperature structural alloys have been developed over a long period of time and have made possible two-phase single-crystal turbine blades that operate at elevated temperatures. The detailed physical reasons why, however, the additional alloying elements improve nickel-base superalloys has not yet been elucidated in detail.

• To commence this research program we studied the temporal evolution of the nanostructure of Ni-Al-Cr, Ni-Al-Cr-Re, and Ni-Al-Cr-W alloys using conventional atom-probe tomography. In this research we also employ transmission electron microscopy to determine precipitate size distributions (PSDs), number denisyt of precipitates, supersaturations of each element, and mean precipitate radii (<R(t)>. Specifically, the temporal evolution at 873 K of a Ni-Al-Cr alloy with moderate supersaturations of Al and Cr was studied in excruciating quantitative detail. Basically we studied the kinetics of a first-order phase transformation, where the temporal evolution of the chemistry of the alloy as well as the nanostructure is quantitatively measured to obtain a detailed physical picture. This is accomplished by aging specimens in the two phase region, g (f.c.c.) matrix plus g’(L12) precipitates, for different times and measuring the chemistry of both phases, the mean radius, <R>, the number density, Nv, and the morphology of the g’(L12) precipitates. For the alloy compositions studied the lattice parameter misfit is close to zero and hence the g’(L12) precipitates remain spheroidal for times as long as 1024 hours. By measuring all of these parameters from the earliest possible aging times we obtained a complete physical picture of the temporal evolution and found experimentally the kinetic pathways. Additionally, we were able to compare our experimental data with the temporal predictions of the Kuehmann-Voorhees model of quasi-state coarsening of a ternary alloy for <R>, Nv, and the supersaturation of the solute elements (Al and Cr) in the matrix. Furthermore, we were able to show that the composition trajectory of the g’(L12)-precipitate phase is not along the tie line connecting the g’(L12) and g (f.c.c.) phases, while the composition trajectory of the g (f.c.c.) phase is along the tie line. An analysis of the compositions of the g’(L12) phases demonstrated a capillary effect for small precipitate radii; the smallest radius measured was 0.45 nm, which corresponds to a precipitate containing 20 atoms. Also the chemical widths of the g’(L12)/g (f.c.c.) interfaces were measured and shown to be broader than anticipated, which is an important unanticipated effect. Finally, using the classical definitions of radial distribution functions (RDFs) in direct lattice space, we were able to demonstrate that in the as-quenched state there is short-range ordering of Ni and Al atoms, which is the precursor to the g’(L12) precipitates that we detect at 600 seconds in the atom-probe tomographic reconstructions. This information permitted an upper bound



(Past and Present),

63

to be placed on the critical nucleus radius of 0.45 nm, which does not depend on a knowledge of the interfacial free energy or the supersaturation and is independent of a model. Finally, an analysis of the experimental data permitted a value of the g’(L12)/g (f.c.c.) interfacial free energy to be calculated. The many results obtained from this study are the most complete ones obtained for a binary or ternary decomposing alloy.

• In parallel with the experimental studies on the decomposition of the ternary Ni-Al-Cr alloy discussed above a vacancy-medaited lattice kinetic Monte Carlo (LKMC) simulation study was performed, which permitted a greater understanding of the experimental results as there is a symbiotic relationship between the two approaches to this problem. The LKMC studies involve the use of one monovacancy in a lattice of atoms bound together by pair-wise potentials out to fourth nearest-neighbor atoms and monovacancy-atom interactions to first nearest-neighbor atoms. LKMC simulations have the important virtue that a physical time is determined as opposed to the use of the Metropolis algorithm MC simulation, where the time is nonphysical and depends on the speed of the computer used. Thus, LKMC results are directly comparable to experimental results after being normalized to the vacancy concentration in pure nickel at the aging temperature.

• The LKMC results have demonstrated, among other things, that the occurrence of necks

between gamma prime precipitates is controlled by the vacancy-solute binding free energy; that is, when the vacancy-solute binding energy is set equal to zero at second, third and fourth nearest-neighbor.positions the necks disappear. The vacancy-solute binding energy also controls the width of the g’(L12)/g (f.c.c.) heterophase interface. With the vacancy-solute binding free energy present to fourth nearest-neighbor positions the width determined by the LKMC simulation is close to the experimental width, whereas in the absence of the vacancy-solute binding energy at at second, third and fourth nearest-neighbor positions the width is narrower. The necks play an important role in the coarsening mechanism of gamma-prime precipitates, which is different from the classical evaporation-condensation model that is implicit in the Lifschitz-Slyozov-Wagner (LSW) model of coarsening, where large precipitates grow at the expense of small precipitates. The coagulation-coalescence model discovered via experiments and the LKMC simulations operates even when the gamma-prime precipitates have similar radii. The KLMC simulations demonstrate that the existence of the off-diagonal terms in the diffusion matrix, which involve significant amounts of diffusive fluxes are important. The presence of these diffusive fluxes was discovered by including a non-zero value for the chemical potential of the vacancy, which is physically reasonable since the inter-precipitate distance is small compared with the distance between the predominant sources and sinks of vacancies, dislocations.

• A key question for any first order phase transformation is: How does a uniform solid-

solution decompose into two phases? This question has been answered experimentally, employing atom-probe tomography, for a Ni-Al-Cr alloy that decomposes at 873 K. The kinetics of clustering are detected employing radial distribution function (RDF) analyses of the solute atoms in direct lattice space. The APT results show the existence of a precipitate at an aging time of 600 seconds using isoconcentration surfaces to delineate the gamma-prime precipitates. For times shorter than 600 seconds RDF analyses centered on the solute atoms, Al and Cr, demonstrated that in the as-quenched state there is already Ni-Al ordering present, the precursor to ordered Ni3(Al1-xCrx) precipitates, which becomes stronger with increasing time with Al substituting for Cr in the domains. As the aging time progresses the domains evolve into visible precipitates of Ni3(Al1-xCrx) (L12), detected via isoconcentration surfaces. Thus the genesis of a new phase has been followed, in direct lattice space, from the quenched-in state to the direct observation of precipitates. The uniqueness and strength of this approach is that it does not depend on deconvolution of data recorded in Fourier space.

• In collaboration with my colleague Prof. D. C. Dunand (Northwestern University), which commenced in 1998, I started a program on the study of the Al-Sc-X system, where X is a ternary alloying element. This research involves a combined study of the high-temperature creep properties between 0.6 and 0.7 of the absolute melting point of pure aluminum, with the characterization of the microstructure utilizing atom-probe tomography, transmission electron and scanning electron microscopies. Scandium has the highest strengthening effect, on a per atom basis, of all the elements in the period table that dissolve in Al. The reason for this is that the phase that precipitates out of single-phase Al-Sc solid-solutions is Al3Sc (L12) and this phase has a melting point greater than 1300 oC. Al3Sc precipitates coarsen at elevated temperatures but they do not dissolve like precipitates in the common age-hardening aluminum alloys, for example, the widely utilized Al-Cu alloys that are used for engine blocks in motor vehicles. We proceeded to study Al-Sc-Mg and Al-Sc-Zr alloys and discovered that the latter alloy forms Al3(Sc1-xZrx) precipitates with an Al3Sc core surrounded by a Zr shell. This shell acts as a diffusion barrier and decreases the coarsening kinetics significantly with respect to the coarsening behavior of Al3Sc precipitates in Al-Sc and Al-Sc-Mg alloys. The high temperature creep properties are determined by climb over the Al3(Sc1-xZrx) precipitates and this results in excellent threshold stresses for creep.

• The next major step in this research involved decreasing the Sc concentrations in the Al-Sc-Zr alloys by substituting rare earth (RE) elements for Sc because they are considerably cheaper and more plentiful in the earth’s crust than Sc. Additionally, we added silicon as it accelerates the precipitation kinetics and is not deleterious to the stability of the alloy if added in small concentrations. We also found that small concentrations of Sb additions serve as a nucleant for precipitates, thereby increasing their number density and concomitantly the alloy’s strength. We have also demonstrated that by a judicious choice of the concentrations of the different alloying elements that the Sc concentration can be significantly reduced without a deterioration in the coarsening kinetics and mechanical properties. We are also able to increase the maximum operating temperature of our Al-Sc-Zr-Er alloys by the addition of Mn and/or Mo.

• Furthermore, at NanoAl LLC, Skokie, Illinois, we have developed high-temperature

aluminum alloys without Sc -- http://nanoal.com/ . I am a co-founder and co-chief scientific officer of NanoAl LLC, which was incorporated in 2013. NanoAl LLC is located in Skokie, IL 60077.

______________________________________________________________________________ • In June 2001 the three-dimensional atom-probe (3DAP) microscope or conventional atom-

probe tomograph commenced working reasonably well; the ultrahigh vacuum system for this instrument was designed and fabricated at Northwestern University and made to work with components purchased from the then Kindbrisk Company, later called Oxford Nanoscience Ltd., which was part of the Polaron plc Company. In 2008 Oxford Nanoscience Ltd. was purchased by Imago Scientific Instruments, Madison, Wisconsin, which reduced the number of manufacturers of atom-probe tomographs in the world to two, Imago Scientific Instruments and Cameca. The latter sold an instrument that was designed and fabricated at the University of Rouen. On April 1, 2010 Ametek, which owns Cameca, purchased Imago Scientific Instruments and discontinued the atom-probe tomograph designed at the University of Rouen and there is now only one source of instruments, Cameca, unfortunately.

• At Northwestern University we purchased from Cameca (December 2004) a local-electrode atom-probe tomograph (LEAP) 4000X Si, which currently utilizes a picosecond ultraviolet laser (wavelength = 355 nm) to dissect specimens essentially one atom at a time. I received recently an ONR DURIP grant, for $1,210,000, to upgrade the LEAP4000X Si to a LEAP5000XS to increase the detection efficiency to 80% from 50%, which is a 60% increase in detection efficiency and to increase the field-of-view. The upgrade will take place in the last quarter of 2017.
