Abstract

Delayed static failure of high-Mn twinning-induced plasticity (TWIP) steels containing various Al contents (0–3.5 wt.%) was studied in the context of hydrogen embrittlement. The roles of residual stress and texture on hydrogen embrittlement were discussed. In the deformed state, Al-added TWIP steels exhibited much better delayed fracture resistance as compared to 0 Al steel, owing to the decrease in the number of diffusible hydrogen-trapping sites coupled with smaller residual stress and strong 〈1 1 1〉 and 〈1 0 0〉 textures.
