Title: Diffusion induced grain boundary migration

Abstract

While grain boundaries and interphase boundaries provide high diffusivity paths in solids, little bulk composition change can occur at temperatures where lattice diffusion is frozen out unless the boundaries migrate. That the diffusion itself can induce boundary migration has been suspected for some time. This study reviews evidence that the effect is indeed common, and this conclusion is reinforced by additional observations on three systems. (GHT)
