· TiAl4Ni5

TiAl4Ni5 is an intermetallic compound based on titanium aluminide with nickel additions, belonging to the family of lightweight, high-temperature metallic materials derived from the Ti-Al phase diagram. This material is primarily of research and developmental interest for aerospace and power generation applications where high strength-to-weight ratio and elevated temperature performance are critical, offering potential advantages over conventional titanium alloys or nickel superalloys in specific thermal regimes, though processing complexity and room-temperature ductility remain areas of active investigation.
