- Abstract
Due to the introduction of hydrogen, there is a serious hydrogen embrittlement problem, which will make the material embrittlement and affect the service life and safety of steel. Therefore, the effect of adding Ti-Mo on the hydrogen embrittlement susceptibility of medium Mn steel was studied in this paper to improve the hydrogen embrittlement resistance. The hydrogen embrittlement susceptibility of 5.6Mn/5.6MnTiMo steel was studied after heat treatment at 670 ℃ for 30 min. The results show that the addition of Ti-Mo can form (Ti, Mo) C carbide to increase the stability of austenite, and the TRIP effect slows down during deformation, so that 5.6MnTiMo steel exhibits higher hydrogen embrittlement resistance. SEM analysis shows that the fracture morphology of the H-uncharged samples is ductile fracture, showing a small hollow dimple. The H-charged samples is “hydrogen-induced” brittle fracture, showed a mixture of solid dimple and intergranular fracture.
