The Al 7075 alloy matrix materials exhibiting excellent mechanical properties with the addition of SiC and B4C particulates as reinforcement. Stir cast method is preferred for preparing composite specimen materials. Then the composites were prepared for heat treatment process by subjecting to solutionizing followed by quenching in different media for improving the mechanical and physical properties. Further, all the specimens are subjected to artificial aging at a temperature of 120˚C for different time duration. The hardness properties are examined for the composite materials before and after heat treatment by brinell hardness test machine. The distribution of reinforcement particles are seen using optical microscope. Due to excellent increase in the hardness the material removal rate decreases. It is also observed that Al 7075 hybrid metal matrix composite experimented under identical heat treatment conditions reveal significant enhancement in hardness.
