Interdiffusivities and atomic mobilities in fcc Cu-Al-Fe alloys

► Interdiffusion coefficients in fcc Cu-Al-Fe alloys at 1273 K were determined. ► Atomic mobilities in fcc Cu-Al-Fe alloys were assessed by using DICTRA. ► The atomic mobilities obtained are reliable. ► Concentration profiles/diffusion paths can be predicted from the atomic mobilities.
