Abstract Scope In presence of hydrogen nickel alloys undergo a ductile-to-brittle transition. A novel nano inverse hydrogen-enhanced decohesion (HEDE) mechanism which takes into account both the influence of hydrogen on cohesion and dislocation emission proposes that for pure Ni this transition occurs in presence of H due to lowering of the stress intensity factor for cleavage (KIc) below the stress intensity factor for ductile dislocation emission and crack blunting (KIe) [Tehranchi et. al. (2020)]. The approach is here extended to binary nickel alloys (with V, Mo, Co, Nb, Ti, W, Fe, Cr) to investigate the influence of alloying elements on HEDE and, in future, to design alloys with reduced hydrogen embrittlement. First-principles calculations were performed to calculate KIe and KIc as a function of solute concentration. Further the critical concentration of H required for each alloy to undergo a ductile-to-brittle transition is calculated and described as a function of the solute nature.
