ABSTRACT

Deep cryogenic treatment technology, as an advanced cold treatment process aimed at improving the performance and service life of metal materials, has attracted widespread attention in the field of materials science in recent years. This technology is not only widely used in the treatment of steel materials, but also shows good treatment effects on non-ferrous metal materials and composite materials. Through cryogenic treatment, the grain size of steel materials is refined, the number of grain boundaries is increased, thereby improving the strength and toughness of the material. At the same time, cryogenic treatment can also promote the transformation of residual austenite into martensite, further improving the hardness and wear resistance of steel materials. In addition, the precipitation of carbides and the adjustment of residual stress during the cryogenic treatment process also play a crucial role in improving the performance of steel materials. However, the impact mechanism of cryogenic treatment on the mechanical properties of steel materials is complex and involves multiple factors. The interaction between grain refinement, residual austenite transformation, carbide precipitation, and residual stress adjustment collectively affects the properties of steel materials. This article explores the influence and mechanism of cryogenic treatment on the mechanical properties of steel materials.
