Abstract

A new model of grain boundary segregation in systems with restricted solubility is proposed. The model is based on the following assumption: As soon as the solute concentration in the grain boundary achieves the bulk solubility limit, embryos of compounds appear in the grain boundary. The composition of these embryos corresponds closely with the nearest phase in the grain according to the phase diagram. The appropriate segregation isotherm taking into account these embryos demonstrates the concentration phase transition which shows itself as a jump in grain boundary concentration. The location and the height of this jump are discussed.
