Grain boundary diffusion coefficient

The grain boundary diffusion coefficient is the diffusion coefficient (during atomic diffusion) of a diffusant along a grain boundary in a polycrystalline solid.[1] At lower temperatures in metals and metal alloys, this diffusion term may dominate the effective diffusion rate.
