Nuclear Materials

Our research is broadly themed around the micromechanics of irradiated and nuclear materials. That is, we try to predict large-scale mechanical behaviors of materials based on our understanding of localized elastic-plastic phenomena associated with atomic- through micro-scale materials constituents/features/phases.  We utilize miniaturized mechanical testing -- often in combination with multi-scale characterization techniques and various modeling approaches -- to understand materials properties and performance.

Our current major research foci can be grouped as follows:  (a) transmission electron microscopic in situ mechanical testing, (b) oxide dispersion strengthened alloys and irradiation evolution of nanofeatures, (c) nuclear materials produced by powder metallurgy and hot isostatic pressing, (d) performance of nuclear weldments under extended irradiation, and (e) technique development.
