· JVASP-104917· Ti3Al5

Ti3Al5 is an intermetallic compound in the titanium-aluminum system, representing a higher-aluminum variant within the titanium aluminide family of materials. This material is primarily of research and developmental interest, used to explore lightweight, high-temperature structural options that bridge conventional titanium alloys and advanced intermetallic compounds. Its appeal lies in potential applications requiring improved creep resistance and elevated-temperature strength compared to standard titanium alloys, though processing and brittleness challenges limit current commercial deployment.
