Abstract

Metal Matrix Composites have wide range of applications in current industrial scenario. Conventional materials have limitations with respect to composite material due to their deficiency in its properties. Composites have lot of scope due to its enhanced mechanical properties like tensile strength, toughness, hardness and compressive strength. The current research includes the study of metal matrix composite of aluminum alloy (A356) reinforced with alumina, graphite and silicon carbide for the application of water cooled cylinder block, which requires good tensile strength, hardness, wear resistance and low coefficient of friction. In the present investigation, 6 primary samples are fabricated with A356 as base metal, where three samples contains the composition of Sic (10%, 15% and 20%), 3% Gr, 10% alumina and other three samples containing Sic (10%, 15% and 20%), and 10% alumina. This study is mainly focused to improve the characteristics like hardness.
