Cryogenic technique has happen to a widely used heat treatment practice for multiple products counting in cutting tools, automobile braking, engine components and aerospace industries. All these sectors at all era desires the materials in condition of light in weight but stronger than viable supplies. This prerequisite is pleased through the preamble of composites. Our work is headed for spotlight on the upshot of profound Cryo treatment on characterizing metallurgical and mechanical property of as cast aluminium alloy at -196 C for different time durations of 24 hours, 37.5 hours and 60 hours. After the profound Cryo conduct of as-cast alloy in liquid nitrogen, the metallurgy of samples showed the transformation in division of precipitate. The modification of microstructure of as-cast aluminium alloy due to cryogenic treatment showed considerable progress in mechanical properties.
