Phenomenological Aspects of Grain Boundary Diffusion
In this paper, the authors review recent progress that has been made in understanding various aspects of grain boundary diffusion at the phenomenological level. We show how the mapping of phenomenological grain boundary diffusion problems onto a lattice readily permits lattice-based random walk theory to be used to address the problem, invariably by Monte Carlo computer simulation methods. Recent advances in calculating concentration profiles and effective diffusion coefficients are described in detail.
