The objective of this review paper is to introduce Cryogenic temperature effect on different properties of materials. Results showed that cryogenic operation improves properties like hardness, fatigue strength, tensile strength, toughness and resistance to wear in comparison to conventional operations. The improvement is a result of microstructural changes at cryogenic temperature which helps in conversion of austenite to martensite and carbide nucleation. The results also showed that doing tempering before or after cryogenic operation has significant influence on material properties which helps to achieve better carbide distribution. Different heat treatment sequences which involve tempering before or after Deep Cryogenic Treatment (DCT), provides varied results. Soaking time at cryogenic temperature also has an important role in refinement of microstructure and affect material properties.

Nowadays, deep cryogenic treatment (DCT) is taken as a promising technique for improving the performance of steel. This article is focused on the influence of different heat treatment processes involving DCT on the microstructural evolution of a high Cr-Co-Mo high-temperature-bearing steel. Moreover, a multiphysical field coupling numerical model is built to investigate the martensitic transformation kinetics during DCT. The results show that DCT significantly improves the hardness and promotes the transformation of retained austenite to martensite at low temperatures. DCT not only refines the retained austenite as thin-film morphology but also increases the precipitation of carbides and induces the carbides more homogenous distribution. This indicates that DCT promoted the segregation of carbon atoms and reduced the carbon content of martensite. The finite element model simulation shows that the retained austenite transformation is still incomplete, and the simulation results agree well with the experimental data by X-Ray diffraction and transmission electron microscope analysis. This implies that the finite element simulation can better reflect and verify the experimental results.
