Eutectic Al-Si alloy metal matrix composite: A Review

Abstract

The Eutectic Al-Si alloy used in automobile parts like engine cylinder, piston due to it good castabilty, high strength properties. Aluminium matrix composite are providing superior properties than the conventional material with ceramics, oxides, boride and minerals as a reinforcement. This paper is presenting a review on AMC composite material which improves the mechanical and tribological properties of base eutectic Al-Si alloy. Special focus is given on to improve the base Al-Si alloy properties with reinforcement at elevated temperature. Graphite wt.% is also reviewed in order to achieve better wear and coefficient of friction resistance. Selection of fabrication method for AMC is discussed
