| Abstract Scope |
The motivation of the nanocrystalline metals community has been to increase microstructural stability to its fullest extent. However, the implication of achieving this end state, i.e. true absolute stability, has not been fully conceptualized. Doing so, provides a new frontier for fundamental discovery where opportunities exist beyond the perceived mechanical limits, which have been called out in this discipline of science. Such a concept raises many new questions related to thermophysical properties especially in extreme environments. This talk will discuss aspect of microstructural rejuvenation and unprecedented damage absorption under intense irradiation, shock loading, and other forms of deformation in the CuTa family of alloys. The collective data shows a unification in response allowing new conclusions to be drawn about the potential of these materials in extreme environments. Finally, with grain boundaries fully stabilized, the next stage of alloy development is presented for CuTa alloys. |
