Based on critically reviewed experimental diffusion data available in the literature, atomic mobilities of Fe, Si, Cu and Zn in bcc_A2 Fe–Cu, Fe–Si and Fe–Zn alloys were assessed as a function of temperature and composition by means of DICTRA simulation package. Semi-empirical correlations were used to obtain the self-diffusivities of Cu, Si and Zn in the metastable bcc_A2 phase. Comprehensive comparisons between calculated and measured diffusivities indicate that most experimental data can be well reproduced by the presently obtained atomic mobility parameters.
► Experimentally-measured diffusivities for bcc_A2 Fe–Si, Fe–Cu and Fe–Zn alloys available in the literature were critically reviewed.
► The self-diffusivities for Si, Cu and Zn in hypothetical bcc_A2 phase were evaluated by employing semi-empirical relations.
► Atomic mobilities of Fe, Cu, Si and Zn in bcc_A2 Fe–Si, Fe–Cu and Fe–Zn alloys were assessed by using DICTRA.
