Diffusion in Al-based alloys is a practical topic that is essential to guide the design of materials. Based on various kinds of experimental diffusivities and thermodynamic parameters, the atomic mobilities in fcc Al–Ag alloys have been assessed as a function of temperature and composition using the DICTRA software package in this work. The calculated results are in good agreement with the experimental data. In addition, the obtained mobility parameters can reasonably predict the concentration profiles for a variety of diffusion couples in fcc Al–Ag alloys.
► The atomic mobility in fcc Al–Ag alloys is assessed in the present work for the first time.
► The optimized mobility parameters predict reasonable concentration profiles of the binary Al–Ag diffusion couples.
► This work complements the kinetic database of the Al-based alloys.
