Nanolayered, self-healing radiation resistant materials
EMSL Project ID
44724
Abstract
Recent discovery and research indicate that materials can be hardened against radiation damage by building nanolayered structures with an optimized layer thickness to increase point defect recombination relative to a non-layered structure and that these nanostructures can self-heal to some extent. This project will develop the fundamental physics of radiation damage for nanolayered shielding materials based on our understanding of the layered atomistic structures, including strain gradients and interface physics, in a radiation field. Experiments will be carried out to understand the radiation effects on multi-layered Al-Ti, Al-V, and Cu-Nb metal films generated at EMSL. In addition to these films, we will obtain O and N processed polymer-derived ceramics SiC nanomaterials from University of Washington (Prof. Raj Bordia) to include nanoscale ceramics in our study.
