| Abstract Scope |
It is known to all that hydrogen embrittlement of metallic materials has plagued the scientific community for many years. Compared to other metallic materials, high-entropy alloys show excellent properties such as high hardness, high strength, heat resistance, and corrosion resistance. Up to now, there is little information focus on hydrogen induced degradation of high-entropy alloys. The influence of hydrogen on the mechanical and deformation behavior of several face-centered cubic high-entropy alloys was examined through tensile tests, EBSD, ECCI. The tensile ductility was reduced by hydrogen charging. The failure mode of the interstitial HEA in presence of hydrogen was a combination of intergranular and transgranular fracture as well as microvoid coalescence. Moreover, the reasons for this were further discussed. |
