Introduction:

Materials and processes have been the key issues for successful design, production and service of any product. It has become inevitable to carry out materials selection and process selection concurrently during the conceptual design itself. On the other hand newer materials have been flooding the materials library. Engineering materials have become engineered materials. We are living in an era of exotic materials which have been synthesized for advanced applications like aerospace. Moreover, there has been a paradigm shift in manufacturing methodologies which are now becoming materials oriented. In addition, advanced manufacturing processes have been developed to achieve commercially viable route for processing new age materials.

The current assignment has been set so that the students get a feel of the materials used in a

typical engineering environment. It is aimed at developing an understanding of interrelationship between material properties and manufacturing processes. The student should select candidate materials for particular applications, recognizing the relative merits and limitations of materials and also suggest appropriate manufacturing methods.

Part-A

Problem statement Many of our modern technologies require materials with unusual combination of properties that cannot be met by the conventional metal alloys, ceramics and polymeric materials. A metal matrix composite (MMC) is a macroscopic combination of two or more distinct materials, having a recognizable interface between them. MMCs are used not only for their better structural properties, but also for improved electrical, thermal and tribological properties. Modern Metal Matrix composites (MMCs) are usually optimized to achieve a particular balance of properties for a given range of applications. But these composites have economic, environmental and manufacturing issues. MMCs are costlier and difficult to recycle or dispose.

In this background a statement is made as “Metal Matrix Composites are designer’s choice for Engine parts” Debate on above statement. Support your opinion with examples, illustrations and case studies. Following points to be considered in this discussion

• Properties and performance of metal matrix composites • Manufacturability • Cost, environmental issues.

Part-B Problem statement

A wind mill is a machine that converts wind into usable energy through the rotation of a wheel made up of adjustable blades. The purpose of wind mill is to convert the energy of wind into rotational energy thus generating electricity. Today wind mill technology is experiencing a revival and wind energy promises to be an important alternative to fossil fuels in the future. Carry out Liturature survey and

1) Identify Important five parts (apart from rotor hub) of wind mill and its functions 2) List and analyze important material property requirement of these parts 3) Comment on materials used with justification

30 Marks

Part-C

Problem statement Selection of materials and manufacturing technique while designing the components is a challenging task. The selection of materials for any component must be made on the functionality of the component and also the manufacturing aspects including the joining of the parts in the final assembly. Cambridge Engineering Selector (CES) is a useful tool in selecting the materials and also their manufacturing processes. Wind turbine consists of rotor hub to which blades are attached externally. The rotor hub is provided for coupling blades and the rotor shaft. It is one of the critical parts of wind turbine. You are required to

1. Select a suitable material for rotor hub of a wind mill using CES 2. Critically analyse the characteristics of selected material based on suitability to its application 3. Select suitable process for rotor hub manufacturing (include primary and secondary

processes) 4. Critically analyse and justify the processes selected

CES screen shots are to be pasted as per relevance and a brief description should accompany each Figure for evaluation. 35 marks

Guidelines for Submission Citation of the references in the text is necessary in all the parts. Part B & C:

• Restrict your report for Part-B and C to a maximum of 12 and 20 pages respectively • Divide your discussions clearly as per the sections mentioned above and draw the conclusion

at the end of each section. • Please note: Marks will be awarded only to the sections and sub-sections clearly indicated

as per the problem statement.
