Abstract
Studies of the effect of radial-shear rolling and subsequent aging on the structure, mechanical properties and creep of VT22 titanium alloy have been carried out. It is shown that the modification of the structure by radial-shear rolling in the temperature range 1123–1023 K and subsequent aging at a temperature of 773 K makes it possible to increase the strength properties of the VT22 alloy under tension in the temperature range 293–773 K by 40–30% compared to the initial state. Under creep conditions an increase in the creep resistance of the modified structure is observed at stresses below 0.5 of the yield stress.
