The microstructure of a material plays a role in determining its properties, and microstructural control is critical in optimizing properties for applications, both structural and functional. Our work focuses on the kinetics of the mechanisms by which microstructure develops during material processing and by which microstructure, and consequently properties, may be unstable. We consider both microstructures that form through solidification and those that form on solid-state processing. Particular interests are: grain refinement of casting alloys, and novel nano-scale structures derived from metallic glasses.
