The present disclosure relates to new titanium alloys and methods for making the same. The new titanium alloys generally include 4.75-6.75 wt. % Al, 6.5-8.5 wt. % (Nb+Ta), 1.5-3.5 wt. % Sn, up to 5.0 wt. % Zr, and up to 2.5 wt. % Mo, the balance being titanium, optional incidental elements, and impurities. Due to their composition and methods of manufacture, the new titanium alloys may find use in several applications, such as aerospace and/or automotive applications.

Titanium alloy products and methods of making the same

A titanium alloy may be characterized by a good oxidation resistance, high strength and creep resistance at elevated temperatures up to 750&#xb0; C., and good cold/hot forming ability, good superplastic forming performance, and good weldability. The alloy may contain, in weight percent, aluminum 4.5 to 7.5, tin 2.0 to 8.0, niobium 1.5 to 6.5, molybdenum 0.1 to 2.5, silicon 0.1 to 0.6, oxygen up to 0.20, carbon up to 0.10, and balance titanium with incidental impurities.
