摘要：

The method of extraction of segregation term from a triple product of grain boundary (GB) diffusion is proposed. The general solution of quasistationary Fisher's model including segregation terms is obtained. The analytical solutions for the saturation and inhomogeneity segregation in GB are obtained. The influence of different type of segregation on GB diffusion is discussed.
