Research Abstract

Micro-tension testing combined with metallographic characterization was used to investigate the effect of martensite on the hydrogen embrittlement mechanism. The underlying microstructure deformed in the presence of hydrogen strongly influences the formation of α’ martensite, leading to premature plastic instability. In both the austenite-phase specimen and the martensite-phase specimen, the microstructure obtained by plastic deformation with hydrogen exhibited low yield stress and poor ability of strain hardening when compared to the counterpart formed in the absence of hydrogen. These findings suggest that defects induced by deformation with hydrogen have a big impact on hydrogen degradation of metastable austenitic steel.
