Abstract :

A Metal Matrix Composite (MMC) is a composite material which is formed of at least two individual parts, one necessarily being a metal and the other constituent may be a ceramic material. A metal matrix composite is fabricated by using metals like aluminium, magnesium etc. (which are generally of low density) with ceramic reinforcements like silicon carbide (SiC), aluminium oxide (Al_2O_3) or minerals like mica, graphite etc. MMC produced have improved tensile strength, higher wear resistance, higher operating temperature, greater stiffness etc. as compared to the individual metallic element. MMC offer a great change in the mechanical, electrical, structural and even magnetic properties which can be studied and can be further used in various industries and fields like aerospace, marines, jet engines, satellites, automobiles etc. Modern world has introduced various methods of reinforcement addition into metal like stir casting, squeeze casting, physical vapour deposition (PVD), chemical vapour deposition (CVD), in-situ fabrication, powder metallurgy etc. The present paper reports a review on the structural and mechanical behaviour of aluminium hybrid metal matrix composite. Aluminium matrix composites (AMC) are modern and advanced metal matrix composites (MMC) that can meet the recent increasing demands of various industries. The physical, structural and mechanical properties of aluminium matrix composites have made them useful in fields of aerospace, marines etc. It is necessary to select the right combination of compounds or minerals to reinforce with the metal as it will directly affect the properties of metal matrix composite thus formed. Selection of different constituents will affect the properties of MMC differently and the composition of constituents can also be varied to observe the changing properties of MMCs. This paper describes the various processing techniques and the various research and development activities taking place in the field of hybrid metal matrix composites.
