Abstract

Surface diffusion within intergrain space is studied theoretically with the help of the Onsageristic approach of irreversible thermodynamics. The grains are treated as isotropic elastic half solids. It is assumed that species of one of the grains are capable to leave their equilibrium positions in the parent solid body and then they migrate within the inter-grain space along the surface of their parent body. Decrease of the total accumulated energy is postulated to be a driving force of the diffusion processes.
