摘要：
Stages of cellular precipitation for the supersaturated Pb-Sn solid solutions were analyzed. This was done for almost the whole homogeneity interval. Literary heritage as well as the data of the present authors concerning kinetic and thermodynamic parameters of cellular precipitation for these solid solutions were compared and summarized. It was shown that the segregation factor, which characterizes the impurity atoms behavior at the grain boundary, decreases with solid solution supersaturation increase.
