Abstract
Diffusion mobilities in binary Al-Zn solid solutions are critically assessed by fitting experimental diffusion data with a phenomenological model, called the Diffusion Controlled TRAnsformation (DICTRA) code. Good agreement is obtained with comprehensive comparisons between calculated values and experimental observations. With a thermodynamic description as the key input, the assessed mobility is further validated by three simulated diffusion experiments, that is, one semi-infinite vapor-solid diffusion couple and two long cylindrical diffusion couples.
