DIFFUSION OF CADMIUM IN LEAD.
Abstract
The diffusivity of cadmium in high purity lead single crystals has been measured from 150C to the melting point using tracer and sectioning techniques. Lead self-diffusivity is enhanced by the addition of cadmium. Comparing the diffusion data for several impurities in lead, it is pointed out that the dominant mechanism of solute diffusion, and hence the diffusion rate as well, is determined primarily by the solute valence. It is then considered that the dominant diffusion mechanism of a particular solute is a natural consequence of its degree of interstitial dissolution, and that solute valence plays a major role in determining the energetics of interstitial dissolution.
