  • Self lubricating titanium aluminide composite material
    Patent number: 11619266
    Abstract: A composite material having an alloy matrix including titanium, aluminum, niobium, manganese, boron, and carbon is disclosed. The composite material includes, by atomic percentage, 40.0% to 50.0% Al, 1.0% to 8.0% Nb, 0.5% to 2.0% Mn, 0.1% to 2.0% B, and 0.01% to 0.2% C. The composite material is doped with a solid lubricant such as MoS2, ZnO, CuO, hexagonal boron nitride (hBN), WS2, AgTaO3, CuTaO3, CuTa2O6, or combinations thereof. Components composed of the composite material exhibit increased ductility at room temperature and reduced fracture tendency, resulting in improved durability.
