Abstract
Diffusion in the Ag-Zn-Cd system was investigated at 600°C with semi-infinite, vapor-solid couples in order to evaluate intrinsic diffusion coefficients and interdiffusion coefficients in theα andβ phases. Intrinsic diffusion coefficients were determined at several composition points in theα-phase region along concentration lines of 11 at. pct Zn, 18 at. pct Zn, 5 at. pct Cd, and 9 at. pct Cd. Interdiffusion coefficients in theα phase were determined at several points of intersection of various composition paths; these composition points of intersection were along lines of constant zinc-to-cadmium concentration ratios of 3.8, 1.8, and 1.2. All two-phase diffusion couples developed planar β/α interfaces. Intrinsic coefficients were computed at three composition points in the β region corresponding to a silver concentration of approximately 55 at. pct. Intrinsic coefficients for β alloys are two to three orders of magnitude larger than those for α alloys.
