Enhanced Diffusion in γ-Fe and Au by Vacancies Induced under Elevated Hydrogen Pressure

Abstract:

Article Preview

Diffusion in a metal under an elevated hydrogen pressure is interesting in view of the fact that the diffusion is enhanced owing to the injection of a large amount of vacancies into the metal. This is peculiar to an elevated hydrogen pressure because diffusion in a metal is generally suppressed under a hydrostatic pressure. In the present article, the effect of an elevated hydrogen pressure on interdiffusion and impurity diffusion is reviewed in the Au-Fe system which has a large difference in the hydrogen solubilities between g -Fe and Au under an elevated hydrogen pressure.
