Nanostructured alloys for extreme conditions

The development of new nanostructured materials for use in extreme mechanical and thermal environments is likely to be of critical importance for a number of future energy technologies. These materials are characterized by a large density of grain boundaries. Consequently, they are inherently strong due to GB strengthening, and they offer resistance to radiation damage due to their high density of unbiased, unsaturable sinks. In this thesis dissertation, it will discuss (i) the mechanisms that control their strength, including inverse Hall-Petch behavior; (ii) their dimensional and phase stability during irradiation; and (iii) the processing of these materials by severe plastic deformation. The work was a combination of both experimental and computational investigations.
