ABSTRACT
Aluminium matrix composites which are new in the category of metal matrix composites have wide potential of satisfying present industrial needs. Aluminium has low density and has capability to resist corrosion hence its matrix composites have become significant matter of concern in the field of metallurgy. The reinforcing materials for the fabrication of aluminium matrix composites could be in the form of whiskers, particulates or fibres, their volume fractions ranging up to 70%. Different properties of the composites can be obtained depending upon the industrial applications by following different processing routes and reinforcements. Certain combinations of reinforcements and processing routes have also been conceptualized for the design of AMC’s. These have wide range of applications including defense, aerospace, sports, automotive due to their low density and highly precise mechanical properties. This paper attempts to review the various processing techniques for the fabrication of AMC’s and their applications. Description of microstructure and the change in the properties of the material together with intrinsic and extrinsic effects are summarized in the paper.
