Interdiffusion in the diffusion couples of metallic multilayers was investigated for the variation of mobility and different initial phase separation states. A phase field simulation showed that the diffusion flux and interface movement increased for higher atomic mobility. The shorter initial phase separation time influences the diffusion flux of two-phase diffusion couples, and had almost no influence upon the interface movement.
