Titanium-based alloy and method for manufacturing a titanium-based alloy component by an additive manufacturing process

A An alpha-beta titanium-based alloy comprising:

• titanium;
• 0.001-1.0 wt. % gadolinium (Gd);
• and
• at least one of aluminum (Al), zirconium (Zr), tin (Sn), oxygen (O), molybdenum (Mo), vanadium (V), niobium (Nb), iron (Fe), and chromium (Cr) 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 %).
