Advanced Manufacturing of High-Entropy Alloys as Cost-Effective Plasma Facing Components for Fusion Power Generation
Project Innovation + Advantages:
Los Alamos National Laboratory (LANL) aims to use additive manufacturing techniques to develop novel W-based high-entropy alloys (HEAs) with compositions and microstructures optimized for ideal performance in PFCs. Atomistic simulations and high-throughput additive processing characterizations will guide manufacturing of these materials. LANL’s project will investigate the HEA PFC performance under fusion relevant conditions, characterizing irradiation resistance, thermal stability, thermoelastic properties, and thermomechanical properties. Scale-up will entail the use of laser powder-bed fusion additive manufacturing to fabricate more complex parts. This project’s findings will be invaluable for the initial down selection of novel PFC candidate materials in various fusion reactor designs.
Reliable PFCs will reduce maintenance downtime in fusion power plants and increase first-wall reliability, making fusion power generation more cost-effective, economically predictable, and commercially attractive.
