| Abstract Scope |
A three-element medium entropy alloy (MEAs) WTaV is explored for its potential application as a plasma-facing material (PFM) in fusion reactors. This investigation probes into the advantages of compositional simplification inherent to MEAs compared to conventional high entropy alloys. The streamlined composition of WTaV promises enhanced manufacturability and potentially superior stability. Furthermore, the strategic exclusion of Cr aims to mitigate complex secondary phase formation and radiation-induced swelling, thereby bolstering its durability under the extreme conditions encountered within fusion reactors. Initial microstructural characterization using SEM and EDS indicates promising features in both as-cast and heat-treated samples. Future work will involve advanced characterization techniques such as TEM, APT and irradiation studies to further elucidate alloy`s properties and performance. This research underscores the potential of meticulously designed MEAs to provide a compelling trifecta of efficiency, resilience, and cost-effectiveness for PFM applications, thus paving the way for significant advancements in fusion material science. |
