Diffusion mobilities in the fcc Ag–Cu and Ag–Pd alloys

Based on the available thermodynamic information and diffusion coefficient data of the binary fcc Ag–Cu and Ag–Pd alloys, the atomic mobilities of fcc Ag–Cu and Ag–Pd alloys have been assessed as a function of temperature and composition in terms of the CALPHAD method using the DICTRA software package. The comparison between calculated and experimental diffusion coefficients indicates that most of the experimental information can be satisfactorily reproduced based on the optimized mobility parameters.

► The atomic mobilities of fcc Ag–Cu and Ag–Pd alloys have been assessed. ► Most of the experimental information can be satisfactorily reproduced. ► The Ag–Cu binary diffusion couple reported in the published literature can be predicted.
