Hydrogen embrittlement (HE) in certain {beta}-Ti alloys has been conclusively attributed to either the formation of a brittle hydride or the raising of the ductile to brittle transition temperature (DBTT) by hydrogen. Yet there remains a need to understand the mechanism(s) governing HE in solution heat treated + aged (STA) metastable beta alloys that do not show either of these two phenomena. Therefore, the possibility of additional mechanisms needs to be addressed to understand HE of {beta}-Ti alloys at these intermediate H concentrations.
