Ti3Ni is an intermetallic compound in the titanium-nickel system, representing a distinct phase in the Ti-Ni binary alloy family. While less common than equiatomic NiTi shape-memory alloys, Ti3Ni is primarily of research interest for understanding phase stability and mechanical behavior in the Ti-Ni system, with potential applications in high-temperature structural components where intermetallic strengthening and low density are advantageous. This material is notable for its use in fundamental materials science studies of phase transformations and as a reference compound for optimizing commercial Ti-Ni alloy compositions.
