“…In view of the correspondingly low densities of the specific states associated with the cores of these defects, information on the properties of the cores can be obtained only under exceptional circumstances. The specific states localised in the dislocation cores or at interfaces can be investigated by a method proposed by the present author [1], in which use is made of:…”

This paper is concerned with diffusion in grain boundaries with non‐equilibrium structure formed during the interaction of grain boundaries with lattice dislocations and discusses problems of the experimental analysis and evaluation of the grain boundary diffusivity taking into account grain boundary structure recovery and possible development of grain boundary migration. Experimental data are discussed on the acceleration of diffusion in grain boundaries after a non‐equilibrium structure has been formed by a specific treatment of the material: after cold pre‐straining and after a superfine grained structure has been formed. Data characterizing the grain boundary diffusivity under high‐temperature deformation are analyzed. In conclusion, some important theoretical and experimental aspects of diffusion along non‐equilibrium grain boundaries are emphasized.

Abstract:The annealing-time dependence of the electrical conductivity of multilayered single-crystal and polycrystalline metal films has been analyzed theoretically within the frame of the semi-classical approach. It is demonstrated that changes in the electrical conductivity which are caused by the diffusion annealing allow for investigating the processes of the bulk and grain-boundary diffusion, and for estimating the coefficients of the diffusion. The electrical conductivity was calculated and the numerical analysis of the diffusion-annealing time dependence was performed at various parameters.
