Metal matrix composites (MMCs) are natural materials of choice for wear sensitive applications. Attractiveness for making MMC components comes from the ratio of the material’s strength to mass although at the expense of ductility. Machining of such components becomes very difficult on account of the material’s wear resistance. Therefore, the ability to cast MMCs into near-net shape components will realize savings. MMCs are being successfully cast with different gravity as well as high pressure die casting (HPDC) techniques[1]. In all these processes porosity originating from dissolved gasses at a high liquid metal pouring temperatures is of great concern.Processing temperatures of liquid metal in semi-solid metal (SSM) casting are much lower, resulting in reduced or even eliminated porosity. Attention has mainly been given to semi-solid casting of aluminum MMCs by the thixocasting route[2−7] but less so to the rheocasting route[8−10]. The aim of this work is to assess the capability of the CSIR–RCS through SiC with various volume fractions reinforced aluminum metal matrix composite and also to investigate consequent wear properties in the as-cast (F) and T6 heat treatment conditions on different abrasive media
