· TaNi3

TaNi3 is an intermetallic compound combining tantalum and nickel in a 1:3 stoichiometric ratio, belonging to the class of high-density metallic intermetallics. This material is primarily of research interest for applications requiring high stiffness and density, particularly in aerospace and high-temperature structural applications where conventional alloys may be insufficient. TaNi3 and related tantalum-nickel phases are investigated for potential use in advanced engine components, wear-resistant coatings, and specialized structural applications, though commercial adoption remains limited compared to established superalloys and refractory metal systems.
