Abstract
Hydrogen effect on an interstitial CoCrFeMnNi high-entropy alloy was investigated by micro-cantilever bending tests with pre-notched {111} plane as a case study. Results showed sharp mode I cracks on (001) plane bisecting two {111} planes in hydrogen-charged cantilevers, which was explained by hydrogen-assisted defects formation and hydrogen pins dislocation motion.
