Bull. Russ. Acad. Sci., Phys. 73, No. 9, 1277-1283 (2009); translation from Izv. Ross. Akad. Nauk, Ser. Fiz. 73, No. 9, 1348-1354 (2009).
Summary: The model of grain boundary diffusion from a permanent source along nonequilibrium migratory grain boundaries is considered. Grain boundary nonequilibrium is characterized by a value of boundary excess energy up to which relaxation goes. It is shown increasing excess energy and migration velocity of nonequilibrium boundaries lead to increasing diffusant volume penetrating into a sample during annealing time.
