Polycrystalline Materials

By Kaitlyn Landram & Jocelyn Duffy

MSE Professor Gregory Rohrer and Robert Suter, Emeritus Professor of Physics with a courtesy appointment in MSE, have uncovered new information that will help materials scientists to predict how the properties of materials change in response to stressors such as elevated temperatures. Using near-field high energy diffraction microscopy (HEDM), they found that the established model for predicting a material’s microstructure and properties does not apply to polycrystalline materials, and a new model is needed.
