“…These clusters act as nuclei for the formation of fine carbides when stress is subsequently relieved. The precipitation of carbides that also occurs during heating from cryogenic treatment temperature is responsible for the residual stress relaxation [36]. The present investigation in tool steel favours this hypothesis for two reasons: (1) the distribution of the carbides in the cryogenically treated samples was more homogeneous than in the non-cryogenically treated samples, and (2) the carbide volume fraction in the cryogenically treated samples was higher than in the non-cryogenically treated ones.…”

“…These clusters act as nuclei for the formation of fine carbides when stress is subsequently relieved. The precipitation of carbides that also occurs during heating from cryogenic treatment temperature is responsible for the residual stress relaxation [37]. The present investigation in tool steel favours this hypothesis for two reasons: (1) the distribution of the carbides in the cryogenically treated samples was more homogeneous than in the non-cryogenically treated samples, and (2) the carbide volume fraction in the cryogenically treated samples was higher than in the non-cryogenically treated ones.…”

“…According to Senthilkumar et al, [13] regarding studies on the effect of cryogenic treatment on the residual stress state in 4140 steel the lower temperature and longer soaking time in DCT promote higher compressive stresses (−184±30 MPa). With reference to the preceding fact it was pointed out by Bhadeshia that the strains due to phase transformations can alter the state of residual stress.…”
