摘要：

A model is developed to calculate the extent of solid state diffusion effects during and after solidification. Ternary diffusivities of Ge and Au in Fe-Ni were measured for use in the calculation procedure. The equilibrium partition coefficients K**X for element X are 0. 43 for Au, 0. 58 for Ge, 0. 12 for P, 0. 87 for Ni, and 1. 45 for Pt. Solid state diffusion effects are significant when the diffusivity of the third element is higher than 1 multiplied by 10** minus **1**0 cm**2/s at 1300 degree C.
