... to as hydrogen embrittlement), liquid-metal embrittlement, and solid metal induced embrittlement. In general, these different phenomena show many similarities, and it would at first seem appropriate to propose an all-encompassing mechanism to account for these behaviors. For example, all of these phenomena...
