Mechanical Properties of Al-SiC Metal Matrix Composites Fabricated by Stir Casting Route

Abstract

Aluminium and its alloys possess excellent properties such as low density, good plasticity and ductility. They find extensive applications in aeronautics, astronautics, automobile and high speed train fields. The matrix alloy, the reinforcement material, the volume and shape of the reinforcement, the location of the reinforcement, and the fabrication method can all be varied to achieve required properties [1]. Metal matrix composites (MMCs), such as SiC particle reinforced Al, are one of the widely known composites because of their superior properties such as high strength, hardness, stiffness, wear and corrosion resistance. SiC particle reinforced Al based MMCs are among the most common MMC and available ones due to their economical production [2]
