Relations Between Diffusion Paths and Interdiffusion Coefficients in the Ternary System Fe-Co-Ni

摘要

Possible interrelations between diffusion paths and interdiffusion coefficients in the system Fe-Co-Ni are analyzed. It is found that the apparition of a straight line shape of diffusion paths imposes strong demands on the values of the conventional interdiffusion coefficients calculated from the experimental data. The possible consequences of this finding are discussed.
