Abstract
Measurements of the effects of alloying lead with silver and palladium on the diffusivity of gold in lead are reported. It is observed that both Pd and Ag strongly de-enhance Au diffusion in lead; in fact, the Pd de-enhances Au diffusivity in Pb more pronouncedly than alloying lead with gold. It was found that the binding energy between a Au tracer in an interstitial site and Pd, Au, or Ag atoms in substitutional sites to form substitutional dimers was the same in all three cases.Keywords
