Grain growth has been a subject of study in the processing and microstructure of materials for many years. Recent advances have focused on three-dimensional topology, three-dimensional microstructure reconstruction and three dimensional kinetic models. Much of our understanding to date is based on assumptions of uniform boundary mobility and surface energy. In this talk I will describe an enhanced framework for study of grain growth when the key factors of mobility, surface energy and curvature are not uniformly distributed in the microstructure. I will present some early modeling results and some ideas for future study.
