Assessment of the atomic mobilities for ternary Al-Cu-Zn fcc alloys

Abundant experimental diffusion data were evaluated to assess the atomic mobilities for the fcc phase of the Al-Cu, Cu-Zn and Al-Cu-Zn systems. Comprehensive comparisons show that good agreements were obtained between calculated and experimental values not only for the diffusion coefficients, but also for diffusion/solidification processes resulting from interdiffusion, such as the Kirkendall shift and solidification curve.
