Patent ID: 11486025

Abstract:
An alpha-beta titanium-based alloy including titanium; one of 0.001-1.0 wt. % neodymium, 0.001-1.0 wt. % dysprosium, or 0.001-0.5 wt. % erbium; and at least one of aluminum, zirconium, tin, oxygen, molybdenum, vanadium, niobium, iron, and chromium present in amounts defined based on an aluminum equivalent and a molybdenum equivalent, wherein the aluminum equivalent (Al-eq) is between 0 to 7.5% and the molybdenum equivalent (Mo-eq) is between 2.7 to 47.5, and wherein the aluminum equivalent (Al-eq) and the molybdenum equivalent (Mo-eq) are defined, in weight percents, as follows: Al-eq=(Al %)+(Zr %)/6+(Sn %)/3+10*(O %)Mo-eq=(Mo %)+0.67*(V %)+0.33*(Nb %)+2.9*(Fe %)+1.6*(Cr %).
