Abstract

Computational results are presented indicating that atom for atom, lithium is four times and helium is eight times more embrittling in a nickel GB than hydrogen. The results also imply that both species must be considered when attempting to determine conditions under which embrittlement would be expected and that models describing the transport of both species in and around the grain boundaries are needed.
