Abstract

The invention discloses an yttrium-modified TB2 titanium alloy which is composed of the following components in percentage by weight: 2.5-3.5% of Al, 4.7-5.7% of Mo, 7.5-8.5% of Cr, 4.7-5.7% of V, 0.005-0.1% of Y, and the balance of Ti and inevitable impurities. The rare-earth element Y is added to perform alloying treatment on the TB2 titanium alloy, so that the rare-earth element Y and impurity elements (C, O, H, N and the like) in the TB2 titanium alloy form rare-earth refractory substances, thereby effectively reducing the distribution of the impurity elements at the grain boundary and solving the problem of grain boundary weakness caused by the impurity elements (C, O, H, N and the like) to some extent. The rare-earth refractory substances have interactions with the recrystallized grain boundary so as to inhibit the motion of the grain boundary, thereby refining the crystal grain and enhancing the strength and plasticity of the TB2 titanium alloy.
