摘要：

The generalized Darken model of interdiffusion is presented. This model is valid for an open and closed system and when intrinsic diffusivities vary with composition. The method of calculation of the intrinsic diffusivities is presented. The practical applications of the model are presented. The intrinsic diffusion coefficients in ternary Cr-Fe-Ni system are determined. Then the evolution of the Cr-Ni steels because of its oxidation is presented, i.e., the interdiffusion in open system due to reaction at the boundary. The computer simulation of interdiffusion process in binary Au-Ni alloy system in which diffusivities markedly vary with composition is shown.
