FIELD: metallurgy.
SUBSTANCE: invention relates to the method of alloying of titanium alloys. The method of thermomechanical treatment of titanium alloy includes the pressure treatment of titanium alloy which comprises plastic deformation at the temperature in the field of alpha and beta phases until equivalent plastic deformation with at least 25% decrease of the cross section area then the temperature of the titanium alloy doesn't achieve and doesn't exceed the temperature of beta transition of the titanium alloy. Further one-stage heat treatment is performed at the temperature, smaller or equal to the beta transition temperature minus 11.1°C.
EFFECT: alloys have high characteristics of strength and impact viscosity.
