Review of cryogenic treatment on metal matric composites

The tool down time is one of the important factors in machine tool industry while machining with the help of different cutting tools. The cryogenic treatment is a one-time permanent, sub-zero heat treatment that entirely changes cross-section of cutting tool. The physical and mechanical properties such as hardness, toughness beside tribological properties such as wear resistance, coefficient of friction, surface finish, and dimensional stability are vastly improved by the cryogenic treatment involving deep freezing of cutting tool materials. Thus, cryogenic treatments on metals and alloys have drawn the attention of researchers. The present review discovers the previous studies those are conducted on LM25-SiC matrix composites specially focusing on deep cryogenic treatment. The review also briefly introduces the concept of deep cryogenic treatment through review their gaps which has been found in previous studies will be analyzed and authenticated in future.
