TO STUDY THE EFFECT OF CRYOGENIC TREATMENT ON SINGLE POINT CUTTING TOOL MATERIALS FOR FINE TURNING
Publication Date : 22/04/2016
Cryogenic treatment (CT) is the supplementary process to conventional heat treatment process in steels, by deep–freezing materials at cryogenic temperatures to enhance the mechanical and physical properties of materials being treated. Cryogenic treatment (CT) of materials has shown significant improvement in their properties .Various advantages like 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. This paper aims at the comprehensive analysis of strategies followed in Cryogenic Treatment process and their effects on properties like TWR, MRR and Roughness on HSS by application of appropriate types of CTs from cryogenic conditioning of the process.
