This book presents various analytical models for boundary diffusion in detail from a didactic points of view. This is followed by a short treatment of the special case of diffusion along small-angle boundaries. Other important aspects discussed at length are the phenomena of diffusion in thin films, diffusion along migrating boundaries, segregation effects, grain boundary diffusion in non-metals and the mechanisms of grain boundary diffusion. Also summarized are the various experimental methods available for determination of the corresponding diffusivities.
