Cryogenic treatment has been recognized by a few methods for expanding apparatus life of numerous cutting instrument materials, hence enhancing efficiency essentially. However genuine components which ensure better instrument execution are as yet questionable. Concentrates on cryogenically treated HSS instruments demonstrate microstructural changes in material that can impact device lives. However little research has been done on other cutting apparatus materials. Cryogenic treatment of carbides presently can't seem to be widely contemplated. This work expects to contemplate the impact of cryogenic treatment on M2 and D2 steels. It is an extension for subzero process and It is the latest technology. The objective of this lecture is to explain the basic transformation of structures and the conversion of retained austenite into martensite and martensite into tempered martensite which in turn include the properties like longer part life, minimize failure because of cracking, enhanced warm properties, better electrical properties including less electrical protection, lessened coefficient of friction, minimal creep and walk, enhanced evenness, and less demanding machining. This retained austenite into martensite is the most important type of transformation i.e. transformation requires diffusion for the changes in crystal structure to occur. The effect of cryogenic process, subzero process, other heat treatment process and the types of heat treatment furnaces structural changes in heat treatment process are studied.
