Nb5Ir7
metal· JVASP-146440· Nb5Ir7
Nb5Ir7 is an intermetallic compound combining niobium and iridium in a fixed stoichiometric ratio, belonging to the family of refractory metal intermetallics. This material is primarily of research and development interest rather than widely commercialized, with potential applications in extreme-temperature structural applications where conventional superalloys reach their limits. The niobium-iridium system is investigated for aerospace and power generation contexts where both high-temperature strength and oxidation resistance are critical, though practical adoption remains limited due to processing complexity and material brittleness typical of intermetallic phases.
