EFFECT OF CRYOGENIC TREATMENT ON VARIOUS TOOL STEELS: A REVIEW

Cryogenic treatment (CT) is a thermal treatment process in steels, by deep-freezing materials at cryogenic temperatures to enhance the mechanical and physical properties of treated materials being treated .Various advantages, increase in hardness, increase in wear resistance, reduced residual stresses, fatigue Resistance, increased dimensional stability, increased thermal conductivity, toughness, by transformation of retained austenite to martensite, the metallurgical aspects of eta-carbide formation, precipitation of Ultra fine carbides, and homogeneous crystal structure, Different approaches have been applied for CT to study the effect on different types of steels and other materials. Steels by application of appropriate types of CTs from cryogenic conditioning of the process. The conclusion of the paper discusses the development and outlines of the trends for the research in this field.
