| Abstract Scope |
The performance of materials in extreme environments poses important fundamental questions about the behavior of condensed matter under far-from-equilibrium conditions. These conditions create challenges in materials design and synthesis. Here, we present a design strategy of novel W-based alloys (including medium and high entropy alloys) for nuclear power applications and elucidate their performance to extreme environments. In-situ TEM thermal stability experiments, mechanical properties and irradiation resistance to single and dual beam irradiations are assessed. The results are elucidated based on theoretical modeling combining ab initio and Monte Carlo techniques. The simulation (CALPHAD, DFT and Cluster Expansion) guided alloys demonstrated outstanding irradiation resistance and high thermal stability and mechanical properties. 3D manufacturing and arc-casting of selected alloys with detailed morphology characterization and correlation with mechanical properties are presented. Finally, we present rate theory and defect property results that describe the mechanisms by which radiation resistant alloys can be designed. |
