AbstractIn this study, cryogenic treatments (-160C) were applied to medium carbon Vanadium content 38MnVS6 steel. The mechanical, and tribological behaviours of steel were investigated. The effects of cryogenic treatment soaking time on the specimens were evaluated in terms of mechanical and tribological performance including impact toughness, hardness, and wear resistance, and microstructural analyses. The results showed that the longer soaking times of cryogenic treatment improved the wear resistance and hardness. But besides the increase of these properties, cryogenic treatment also reduced the impact toughness compared to that of the conventional method, due to the increased in the distribution of martensitic transformation.
