Materials for Extreme Irradiation Environments

We investigate a new approach to design materials that are intrinsically resistant to irradiation and other extreme environments by utilizing nanostructuration and self-organization in nonequilibrium systems.

The research combines irradiation of thin films with controlled chemistry and microstructure, advanced microstructural characterization, and in-situ and ex-situ mechanical testing. Modeling from the atomistic to the macroscopic scale is employed to explore materials response to extreme environments, and to guide the design and the analysis of the experiments. While we focus on nuclear applications, the scientific advancements achieved in this cluster will also impact materials needs in other extreme environments.
