摘要

The technological regimes of receiving of round bars of VT22 titanium alloy with the diameter 22 mm and hierarchically organized ultrafine-grained (nano-) structure by helical rolling and subsequent heat treatment (aging) were developed. It was shown that such structure formation results in a substantial increase (by more than 20%) of strength properties of the alloy as compared to the initial state. The obtained rods with a high specific strength may be used in the aerospace industry in the manufacture of critical structural elements.
