The kinetics of grain boundary segregation in Cu(Bi) alloys has been studied at temperatures of 600 and 850 o C by Auger electron spectroscopy. A substantial acceleration of the grain boundary segregation kinetics in the two-phase area of the Cu-Bi phase diagram is observed. To explain this acceleration, a model of dislocation diffusion is proposed. In the framework of the model, the accelerated...
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...
