EFFECT OF CRYOGENIC TREATMENT ON TOOL STEELS.

Abstract

The objective of this review is to understand the effect of cryogenic treatment on tool life and its performance. As cutting tool life is an important factor in reducing the cost of production. In this process of cryogenic treatment, tools are generally subjected to the process such as heat treatment for achieving the hardness which will improve the performance of the tool to some extent. Cryogenic treatment also known as cold treatment, in which the phase transformation of the material takes place, is mainly responsible for changes in the wear resistance, tensile strength, toughness etc. which increases the tool life. From the review it was understood that has great effect on cutting tool properties. Especially soaking period varied from 6 hours to 36 hours are giving different effect on the phase transformation of the material, consider as one of the important aspect for tool life improvement. Various soaking range namely shallow cryogenic treatment (SCT), Cryogenic treatment (CT) and deep cryogenic treatment (DCT) produce different properties in tool material. This treatment or process can be very useful in case of machinability of work-piece, quality of machining in terms of surface finish and economics of the tooling. Copy Right, IJAR, 2017,.
