The metal matrix composite (MMC) have become the leading material in aerospace and automobile industries and particle reinforced aluminum MMC`s have received a considerable attention due to their excellent mechanical properties like hardness, high tensile strength etc. Aluminum matrix composites refer to the class of light weight high performance aluminum ceramic material systems. The purpose is to study above mechanical properties of Al-6061 with boron carbide and graphite in cryogenic condition by varying boron carbide with 0, 3, 6, 9 and 12% particulate using stir casting process. An improved mechanical property of composites makes them very useful for various applications in many areas from technological point of view. The microstructure and hardness of the fabricated composites were analyzed and reported.
