Both experiment and simulation have been used to characterize microstructures and to predict their properties. In fact, the study is three-dimensional in nature because most practical structural materials have a polycrystalline or multi-phase structure with significant complexity in the spatial arrangement of the microstructural units. This is especially true for metallic and ceramic structural materials, since they are subject to various processes. In Lee’s group, it is of great interest to study process-microstructure-property relationship in multi-dimensions to optimize the materials design and performance.
