Abstract
The basic tendency in improving titanium alloys is the need to increase the specific strength of structures of the aerospace engineering. Owing to the strength of advanced alloys Ti­10­2­3 (the USA) and VT22 (Russia), reaching 1300­1400 MPA, titanium is used widely in the load­carrying airframes and most loaded parts of engines of the modern airplanes ``Boeing'', ``Airbus'', ``Antonov'', ``Ilyushin ``, and others. At present, the problem is to develop alloys with a tensile strength of 1600 MPa and higher. Figs 2, Refs 6.
