Modeling of intergrain diffusion in solids with account for grain surface morphology

An equation for intergrain diffusion accounting for grain surface topology has been derived. The diffusion tensor is proportional to the topological tensor. The extreme properties of the generalized diffusion coefficient in a one-dimensional equation have been studied by means of an approximation of...

Description
Summary:An equation for intergrain diffusion accounting for grain surface topology has been derived. The diffusion tensor is proportional to the topological tensor. The extreme properties of the generalized diffusion coefficient in a one-dimensional equation have been studied by means of an approximation of grain surfaces.
