Abstract
The development and evaluation of a multicomponent diffusion mobility database for Ni-rich alloys are reviewed. In an effort to directly evaluate the mobility parameters in the database, a method for optimizing the mobility parameters as a function of the experimental composition profiles is proposed. This method is demonstrated for the NiCo system at 1100 °C. The optimization of four diffusion mobility parameters improved agreement between the experimental and calculated composition profiles and decreased the error between the experimental and calculated interdiffusion coefficients from 45 to <5%. This method can easily be expanded to multicomponent systems.
