INTRODUCTION

A composite material is defined as a material system which consist

of a mixture or a combination of two or more different materials

which are insoluble in each other and differ in form or chemical

composition.

Composite materials should comprise component materials that are

congenital with each other. In the field of high modulus composites,

resin-matrix composites find considerable interest is easy to

fabricate into engineering structures.

In the case of metal matrix composites, the working temperature is

much higher.hence,both chemical and mechanical harmony are

major issues.

The aim of this chapter is to provide the readers with an

insight into the factors that affects the properties of Al/SiC

composites and the most important response parameters,

associated to mechanical, heat treatment, and corrosion

behavior.

Aluminum silicon carbide alloy composite materials are

widely used for a many number of applications like

engineering structures, aerospace and marine application,

automotive bumpers, sporting goods and so on.

OBJECTIVE

The Metal matrix composites (MMCs) are made by dispersing

a reinforcing material into a metal matrix. The achieving a

homogeneous distribution of reinforcement within the matrix

is one such challenge and this affects directly on the

properties and quality of composite.

Its very light weight, high strength, stiffness and exhibit

greater resistance to correction, oxidation and wear.

In this study hybrid aluminum matrix composite was

fabricated through stir casting route.

Fabrication of Al5083/B4C surface composite by friction

stir processing and its tribological CharacterizationNarayana Yuvaraj a, Sivanandam Aravindanb,Vipina

(Accepted 8 February 2015)

Content:

Improved surface properties with the retainment of bulk properties

are necessary for a component for enhanced wear characteristics.

Friction stir processing (FSP) is used to produce such surface

composites. Fabrication of 5083 aluminum alloy with reinforced

layers of boron carbide (B4C) through FSP was carried out.

Micro and nano sized B4C particles were used as reinforcements.

The friction processed surface composite layer was analyzed through

optical and scanning electron microscopically studies.

The number of passes and the size of reinforcement play a vital

role in the development of surface composites by FSP. Mechanical

properties of the friction stir processed surface composites were

evaluated through micro hardness and universal tensile tests.

LITERATURE REVIEW

Micro structural and corrosion behavior of Al/SiC metal

matrix composites

H.M. Zakaria (Accepted 16 March 20014)

Content:

Aluminum alloys reinforced with ceramic particulates have

significant potential for structural applications due to their high

specific strength and stiffness as well as low density.

These properties have made particle-reinforced metal matrix

composites (MMCs) an attractive candidate for the use in weight-

sensitive and stiffness-critical components in aerospace,

transportation and industrial sectors .

Corrosion behavior is very important parameter for assessing the

application potential of composites as structural materials.

Metal to Metal Worn Surface of AA6061 Hybrid

Composites Casted by Stir Casting Method

K.Umanath,S.T.Selvamani,K.Palanikumar and D.Niranjanavarma(2014)

Content:

Aluminium alloy (AA6061) is reinforced with fine particulates are

produced composite and discussed in this work. The reinforced

aluminium alloy hybrid metal matrix composites (HMMCs) with 5

to 25% vol.

Fractions of Silicon Carbide and Aluminum Oxide reinforcements

were created by stir casting technique. The metal to metal wear

behavior of these hybrid composite and that of un-reinforced alloy

was investigated by pin-on-disc wear testing machine.

The optical micrographs in use for the micro structure investigation

of the hybrid composite show that the Silicon Carbide and

Aluminium Oxide particulates reinforcement are regularly

distributed in the matrix materials.

Study on ageing behaviour of silicon nitride reinforced

Al6061 Composites

Praveen J Mane , K L Vishnu Kumar (2014)

Content:

Aluminium alloy especially 6000 series have the unique property

of undergoing ageing or precipitation hardening due to theformation

of Mg2Si precipitates in the alloy.

The matrix phase of these alloy series when added with

reinforcements like Si3N4 undergo enhanced increment in hardness,

strength and load bearing capacity due to formation of high

dislocation density.

In this investigation the ageing behavior of particulate

reinforcements of Si3N4 particles in Al6061 metal matrix composite

is compared to that of unreinforced Al 6061 base alloy. Both the

composite and base alloy were subjected to ageing at solutionizing

temperature of 525°C and ageing temperature of 195ºC.

Content:

In composites, materials are combined in such a way as to enable us

to make better use of their parent material while minimizing to some

extent the effects of their deficiencies. The simplest term

‘composites’ gives indication of the combinations of two or more

material in order to improve the properties .

To composite materials for adjusting to the global need for reduced

weight, low cost, quality, and high performance in structural

materials.(AMCs) areas of aerospace and automotive industries

include the performance economic and environmental benefits.

Development of Aluminum Based Silicon Carbide Particulate

Metal Matrix Composite

Manoj,S.Dwivedi,D.D.,Lakhvir,S.andVikas,C.(2009)

Content:

The aim involved in designing MMCs is to combine the desirable

attributes of metal and ceramics. The addition of high strength, high

modulus refractory particles to a ductile metal matrix produces a

material whose mechanical properties are intermediate between the

matrix alloy and the ceramic reinforcement.

Metal have a useful combination of properties such as high strength,

ductility and high temp. resistance, but sometimes have low

stiffness, whereas ceramics are stiff and strong, through brittle.

An Investigative Review on Thermal Characterization of

Hybrid Metal Matrix Composites

S. A. Mohan Krishna, Dr. T N Shridhar, Dr. L Krishnamurthy

Content:

Composite materials have become cynosure among all materials that have applications in profusion. The applications of these materials are absolutely appreciative and applicable in almost all areas of mechanical engineering.

The mechanical characterization of these materials has become common nowadays. But the thermal characterization of hybrid metal matrix composites is increasingly important in a wide range of applications.

Aluminium Silicon alloys in particular finds extensive and increased applications in industries due to their properties viz., high fluidity, low melting point, high strength, corrosion resistance, good casting characteristics and lower coefficient of thermal expansion.
