Abstract

Based on the available thermodynamic information and diffusion coefficient data of the Ag-Zn binary system, the atomic mobilities of Ag and Zn in face-centred cubic (fcc) Ag-Zn alloys have been assessed as a function of temperature and composition in terms of the CALPHAD method using the DICTRA software package. Optimized mobility parameters are presented. Comparisons between the calculated and measured diffusion coefficients show that most of the experimental information can be satisfactorily reproduced in the present work. The obtained mobility parameters can also predict reasonable concentration profiles of the diffusion zone in the binary Ag-Zn diffusion couples.
