N2 - The effects of Mn content and grain size on the hydrogen embrittlement resistance of face-centered cubic (FCC) CrCoFeMnNi high-entropy alloys were examined using tensile testing at an initial strain rate of 10−4 s−1. The most important finding of this study was that the combined effect of Mn removal and grain refinement provided nearly complete resistance to hydrogen embrittlement with over 800 MPa tensile strength in FCC high-entropy alloys, even after 100 MPa hydrogen gas charging.
