· JVASP-26092· Ti3Al2NiN

Ti3Al2NiN is a titanium-based intermetallic nitride compound combining titanium, aluminum, nickel, and nitrogen. This material belongs to the family of advanced titanium nitrides and intermetallics under active research for high-temperature structural applications where conventional titanium alloys reach their performance limits. Its appeal lies in potential improvements in creep resistance, hardness, and thermal stability compared to conventional Ti–Al alloys, making it of interest for aerospace and high-temperature engine components, though industrial deployment remains limited pending further development and process optimization.
