The present research work studies the effect of cryogenic treatment on the residual stress state in 4140 steel. Two kinds of cryogenic treatment, namely shallow (SCT, -80 โข C ร 5 h) and deep cryogenic treatment (DCT, -196 โข C ร 24 h) were carried out between quenching and tempering in conventional h
Deep cryogenic treatment (DCT) of tool steels is used as an additive process to conventional heat treatment and usually involves cooling the material to liquid nitrogen temperature (-196 โข C). This kind of treatment has been reported to improve the wear resistance of tools. In this study, the Taguch
