Abstract:

The aluminum matrix composite (AMCs) is considered to be a most suitable material for low and high temperature applications. Particles reinforced AMCs materials have high specific strength and modulus of elasticity due to the reinforcement present in the matrix. In order to get the desired property alumina and chromium oxide are added as reinforcement with aluminium base metal.  Stir-casting route was selected to synthesize the composites as it is considered as the most effective tool in metal matrix preparation .The key mechanical properties such as hardness and wear resistance of the composite was evaluated .Under stir-casting, the alumina and CrO3 were found to be uniformly distributed in the aluminum alloy and bonding between alumina and chromium oxide reinforcement with the aluminum base was effective. The hardness and wear resistance property of the metal matrix composite were compared with Aluminum 6061.
