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 β’ C Γ 5 h) and deep cryogenic treatment (DCT, -196 β’ C Γ 24 h) were carried out between quenching and tempering in conventional h
