Title: Influence of crystallographic orientation, chemical inhomogeneities, material transport anisotropy and elastic strain energy on the migration of grain boundaries in chromium-doped alumina during internal reduction

Abstract

Diffusion-induced grain boundary migration is observed during internal reduction of chromium-doped alumina. It occurs because grain boundary diffusion is fast compared to lattice diffusion of oxygen. The oxygen chemical potential relaxes between grain boundaries and adjacent grains. Migration to either side of the boundary plane or by more rapid oxygen relaxation when the c-axis of a grain is perpendicular to the boundary plane.
