· JVASP-75821· TcAsW2

TcAsW2 is a ternary intermetallic compound composed of technetium, arsenic, and tungsten, belonging to the refractory metal alloy family. This is a research-phase material with limited industrial deployment; it is primarily of interest in specialized high-temperature and radiation-resistant applications where the combined properties of refractory elements offer potential advantages over conventional nickel- or cobalt-based superalloys. The material's notable density and elastic properties suggest potential use in extreme-environment engineering, though its rarity, cost, and the inherent challenges of processing technetium limit its practical adoption to niche defense, nuclear, or advanced aerospace research contexts.
