· JVASP-40318· TaFeRu2

TaFeRu2 is a ternary intermetallic compound combining tantalum, iron, and ruthenium in a fixed stoichiometric ratio. This material belongs to the research-phase high-entropy and refractory metal alloy family, investigated primarily for applications requiring exceptional thermal stability, corrosion resistance, and structural integrity at extreme temperatures. While not yet established in mainstream industrial production, ternary tantalum-based intermetallics show promise for next-generation aerospace, chemical processing, and high-temperature structural applications where conventional nickel or cobalt superalloys reach performance limits.
