Abstract:

Hydrogen embrittlement of niobium has been recently shown to be caused by the stress-induced formation and cleavage of the brittle beta hydride. It is the purpose of this note to review the general requirements for this fracture mechanism and to discuss its applicability to brittle fractures caused by the formation of other phases such as oxides, nitrides, carbides, helium bubbles, etc. It will be shown that this mechanism can play a role in the slow strain rate embrittlement of a variety of different systems.
