| Abstract Scope |
Refractory High Entropy Alloys (RHEAs) have recently emerged as candidate materials for extreme environments such as those found within fusion reactors. These novel alloys can tackle two problems: 1. Irradiation damage in fusion reactors, e.g. fast 14.1 MeV neutrons that cause material embrittlement among other adverse effects. 2. High temperature fusion or atmospheric environments where corrosion can take place. Furthermore, manufacturability has been identified as a key area that can unlock long operational reactor lifetimes. In its mission for sustainable fusion energy production, Avalanche Energy seeks to develop and implement an integrated process for predicting novel refractory alloy systems for dual-use extreme environment applications. Recent material irradiation experiments at the DIII-D tokamak facility showed promising performance. Ultimately, the resulting material systems will provide extreme environment resilience while utilizing advanced manufacturing methods to realize these materials in demanding form factors. These alloys will allow operation of critical infrastructure underwater or on national security critical technologies (e.g. nuclear reactors, aircraft). |
