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.
