The effect of interaction among γ ordered domains on the interdiffusion process in γ + γ /γ and γ + γ /γ + γ diffusion couples is investigated by using the phase-field method, in which bulk free energy and mobility are linked with thermodynamic and kinetic databases. Simulated results show that the interaction among γ ordered domains has great influence on the microstructure, the interdiffusion velocity and the volume fraction of γ phase on both sides of the diffusion couples.
