ON CONTINUUM ASPECTS OF GRAIN BOUNDARY SLIDING AND DIFFUSIONAL CREEP.

Abstract

The problem of sliding at a non-planar grain boundary is considered in detail. The stress field, and sliding displacement and velocity can be calculated at a boundary with a shape which is periodic in the sliding direction (a wavy or stepped grain boundary): (a) When deformation within the crystals which meet at the boundary is purely elastic, (b) When diffusional flow of matter from point to point on the boundary is permitted.
