Using available experimental data in the literature, the atomic mobilities of Ag, Cd and Sn in face-centered cubic Ag–Cd and Ag–Sn alloys were critically explored. The proposed atomic mobility parameters could reproduce a great majority of experimental data, including impurity diffusion coefficients, tracer diffusion coefficients, intrinsic diffusion coefficients and interdiffusion coefficients. The evolutions of composition profiles and Kirkendall marker shifts in Ag–Cd binary diffusion couples were also computationally studied.
