Abstract
The effect of cryogenic plastic pre-strain (15 %, 30 %, and 45 % true strain) on the hydrogen embrittlement (HE) of an equimolar FeNiCoCrMn high-entropy alloy was studied through slow strain rate tension (SSRT) at 1 × 10−5 s−1. As the pre-strain increased, ductility loss under harsh electrochemical hydrogen charging showed a downward trend accompanied by the promotion of hydrogen adsorption. This work provided an effective strategy for achieving the synergy of high strength and improved HE resistance.
