Thermodynamic aspects of the grain boundary segregation in Cu(Bi) alloys
Journal Article

The grain boundary segregation of Bi in dilute polycrystalline Cu-Bi alloys was systematically studied as a function of temperature and composition. The temperature dependencies of the Gibbsian excess of Bi at the grain boundaries exhibited discontinuous changes at the temperatures close to, but different from the bulk solidus temperatures. The observed segregational phase transition was interpreted in terms of prewetting model.
