· Ti5Al21Ni74

Ti5Al21Ni74 is a titanium-nickel intermetallic compound with significant nickel content and minor aluminum alloying, belonging to the titanium-nickel (TiNi) family of materials. This composition represents an experimental or specialized variant within the shape memory alloy (SMA) and high-temperature intermetallic space, potentially developed for applications requiring enhanced strength, thermal stability, or specific transformation behavior beyond conventional equiatomic TiNi. The material is notable for its potential use in demanding aerospace, automotive, and biomedical environments where combination of shape memory properties, damping, or high-temperature capability is required.
