| Abstract Scope |
Refractory High Entropy Alloys (RHEAs) have recently emerged as candidate materials for extreme environments such as those found within fusion reactors and hypersonic systems. These exhibit high melting points, stable mechanical properties and to an extent corrosion resistance. RHEAs can tackle two problems and would include the following: 1. Fusion reactors where irradiation damage is an issue. In particular, 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. 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. The resulting material systems will provide extreme environment resilience while utilizing an advanced manufacturing method using radioactively safe materials. These alloys will allow operation of critical infrastructure underwater or on national security critical technologies (e.g. nuclear reactors, aircraft). |
