Scope The control of polycrystalline grain microstructures of solid materials through processing is crucial to improve their properties, such as strength, toughness and electrical conductivity. This symposium will focus on the understanding and prediction of the thermodynamics and kinetics of grain microstructures during recovery, recrystallization, and grain growth. Recent advances in computational hardware and numerical algorithms have opened up new possibilities for theoretical investigations of these phenomena as they occur in real specimens: namely, in 3D. Moreover, ongoing experimental developments including, atomic resolution methods, orientational imaging, and advanced in situ techniques, are providing quantitative insights and data concerning the development of grain structure and motion of individual boundaries that can further inform and validate the theoretical and modeling approaches. We invite contributions that address these issues and current advances in the field, particularly those that aim to bridge the remaining gaps between experiment and theory.
