Abstract: 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.
