摘要

W-based high-entropy alloys (HEAs) show strong potential as plasma-facing materials but face challenges arising from vast compositional space and inefficient discovery strategies. Herein, we introduce a high-throughput experimental methodology that couples rapid alloy fabrication with parallel multi-sample helium plasma implantation, to discover helium plasma resistant W-based HEAs. A W-Ta-Cr-Mo alloy exhibiting superior helium plasma resistance was successfully identified. Additionally, we provided a high-quality dataset comprising nanofuzz thicknesses of 108 W-based HEAs. Subsequent statistical analysis revealed clear trends: increasing Ta content significantly improves helium plasma resistance, while V shows an opposite effect; moreover, increasing compositional complexity tends to improve helium plasma resistance.
