· V4 Ir4

V4Ir4 is an intermetallic compound combining vanadium and iridium in a 1:1 ratio, belonging to the family of refractory metal intermetallics designed for extreme-temperature applications. This material is primarily of research interest rather than established industrial production, with potential applications in high-temperature structural components where both thermal stability and oxidation resistance are critical, though iridium's cost and scarcity currently limit widespread adoption compared to nickel-based superalloys.
