Effect of alloy element on hydrogen-induced grain boundary embrittlement in BCC iron

Journal of Materials Research and Technology
The strength enhancement usually increases its susceptibility to hydrogen (H) embrittlement in steel materials. However, the atomic-level mechanisms of solutes influence hydrogen behavior at grain boundaries (GBs) remain incompletely understood.
