摘      要：This work explained about the hardness, density and tensile behavior of AMMCs and also recognizes the influence of Cr 3 C 2 into AA7075 under casting process on their mechanical properties. The composites are obtained through stir casting process with 2.5, 5 and 7.5 wt% of Cr 3 C 2 . It is observed that the mechanical properties of the composites are increased with increasing weight percentage of reinforced material. The results are analyzed with optical micro structural images. The optimum hardness and tensile strength were observed at 5 wt% Cr 3 C 2 composite than other wt% of composites as well as monolithic base material.
