摘要：
A model for simulating diffusion in multiphase dispersions is here applied to Ni-Cr-Al multiphase diffusion couples at 1200 degrees C. All simulations are based on the assumption that the gamma-phase is continuous throughout the whole diffusion couple with beta and/or gamma' as secondary phases. Further, the model is incorporated into the DICTRA software, which means that the simulations are based upon critically assessed thermodynamic and kinetic data. Diffusion paths are predicted for several different types of diffusion couple. The simulation results are in general agreement with both experimental as well as theoretical findings and it is concluded that the present model can be applied to predict interdiffusion in important industrial applications, e.g. high temperature coatings.
