· Ta2 Nb1 Ir1

Ta₂Nb₁Ir₁ is a ternary refractory metal intermetallic compound combining tantalum, niobium, and iridium. This is a research-phase material within the high-entropy and refractory metal alloy family, designed to explore ultra-high temperature structural performance beyond conventional superalloys. While not yet established in production, this composition targets extreme-environment applications where thermal stability, oxidation resistance, and mechanical integrity at >1200°C are critical—contexts where traditional nickel or cobalt superalloys reach performance limits.
