Metal matrix composites have evoked a keen interest in recent times for potential applications in many areas, especially aerospace & automotive industries owing to their superior strength to weight ratio. A particle reinforced metal matrix composite consists of uniform distribution of strengthening ceramic particles embedded within metal matrix. Manufacturing of aluminum alloy based composites via stir casting is one of the prominent and economical routes for processing of metal matrix composites. An attempt has been made to synthesize HE-30 Al Alloy-SiC particulate metal matrix composite by liquid metallurgy route. Micro-structural characterization revealed fairly uniform distribution of SiC particles in the matrix. The prepared composite was subjected to the mechanical testing as per ASTM standards. The mechanical tests revealed an increase in hardness and tensile strength of the developed composites over the base metal alloy.
