外文摘要：The effect of temperature-induced martensite (TIM) and deformation-induced martensite (DIM) on hydrogen embrittlement (HE) resistance of austenitic stainless steel (ASS) was comparatively investigated. A considerably higher HE resistance was achieved in the steels with TIM than that with DIM. This may be attributed to a higher density of Geometrically Necessary Dislocation (GND) and a higher proportion of low angle grain boundaries (LAGBs) in the steels with DIM, and a higher fraction of Σ3 in the steels with TIM. LAGBs and dislocations with lower hydrogen binding energy increased the hydrogen diffusion coefficient, thereby promoting the hydrogen absorption/desorption kinetics. While, Σ3 with more regular atomic arrangements and lower interfacial energy reduced fast migration for hydrogen. Accordingly, hydrogen can be captured steadily, promoting the crack propagation along the prior austenite grain boundaries. ? 2026 Elsevier Ltd
