Intrinsic Diffusion and Vacancy Wind Effects in Silver-Cadmium Alloys

摘要

Diffusion in the silver-cadmium system was investigated at 600°C with vapor-solid and solid-solid diffusion couples in the alpha phase fox the determination of intrinsic diffusion coefficients, atomic mobilities and interdiffusion coefficients. Intrinsic diffusion coefficients, Kcd and DAg, determined experimentally, were compared with those predicted from the models of Darken, Manning, and Dayananda with the aid of tracer diffusion and thermodynamic data.
