The diffusional mobilities of Cr, Ni and Si in face-centered cubic Cr-Ni-Si alloys were assessed, as a function of temperature and composition, by means of the computer calculation of phase diagrams. A comparison of calculated and measured diffusion coefficients showed that most of the experimental information could be satisfactorily accounted for by the present modelling. The parameters which were obtained could predict reasonably well the concentration profiles in binary Ni-Si and ternary Cr-Ni-Si diffusion couples.
