· JVASP-155277· Ta3Ni

Ta₃Ni is an intermetallic compound combining tantalum and nickel, belonging to the family of high-melting transition metal intermetallics. This material is primarily of research and academic interest rather than established in high-volume engineering applications, but represents the broader class of refractory intermetallics being investigated for extreme-temperature structural applications where conventional superalloys reach their limits.
