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

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

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. To address this gap, first-principles calculation was...
