A research review on deep cryogenic treatment of steels. (1st January 2014) - Senthilkumar, D.
The effect of deep cryogenic treatment on properties of different types of steels was extensively studied. Cryogenic treatment can convert the retained austenite into martensite along with the carbide precipitation and hence enhances the wear resistance when compared to the conventional heat treatment of steels. It also increases the compressive residual stresses in the component, which leads to better fatigue life. However, this study is carried out to reveal the mechanism of deep cryogenic treatment with respect to different materials, pretreatment conditions and properties of steels for the practical application.
