Abstract
The structure and mechanical properties of high-temperature titanium alloy of Ti–Al–Zr–Si–Mo–Nb–Sn system after hot deformation treatment by various modes were studied. It was found that metal deformation treatment performed in the upper part of the region of (α+β)-phase existence, ensures an increase of material ductility by almost 30 times, compared with lithium, and high strength values, both at room and at working temperature of 600 °С.
