Abstract

Staging of cellular precipitation of Pb-Sn supersaturated solid solutions almost in the whole interval of homogeneity has been analysed. Literary data and the data of the present work on kinetic and thermodynamic cellular precipitation parameters of these solid solutions were compared and generalized. It was found that the segregation coefficient decreases wuth the increase of the solid solution supersaturation. This coefficient determines the behaviour of impurity atoms at grain boundaries.
