Based on various experimental diffusivities of fcc Al-Ag-Zn
alloys available in the literature and the thermodynamic parameter evaluated in the present work,
atomic mobilities of Al, Ag and Zn in the fcc Al-Ag-Zn system were assessed as a function of
composition and temperature with the aid of DICTRA software. Comparison between the calculated
diffusivities and the corresponding experimental data indicates that the presently obtained
atomic mobilities can reproduce most of the diffusivities, such as tracer diffusivities, impurity
diffusivities and interdiffusivities in both binary and ternary systems. The reliability of the
atomic mobilities was further verified via comparisons between the model-predicted
concentration-distance profiles of the binary and ternary diffusion couples and the
experimentally measured ones. Good agreement between the calculated and the measured
concentration-distance profiles indicates that the presently obtained atomic mobilities are
reliable. The diffusion paths can be also reproduced by the presently obtained atomic
mobilities.
