· JVASP-148234· Ta2SiNi3

Ta2SiNi3 is an intermetallic compound combining tantalum, silicon, and nickel, representing a specialized high-performance alloy in the refractory metal family. This material is primarily of research and development interest rather than widely commercialized, with potential applications in extreme-temperature environments where conventional superalloys reach their limits. Its notable characteristics stem from the combination of tantalum's exceptional refractory properties with nickel's strengthening and silicon's solid-solution hardening effects, making it relevant for aerospace and energy sectors seeking next-generation high-temperature materials.
