The method of isothermal forging produced the lot of blades of titanium alloy VT6 at a temperature of 650оC. This temperature on 250оС below usually applied at the production of blades from the alloy of ВТ6. Picked up by thermal treatment of the blades. Research on the microstructure and mechanical properties of the blades. It is shown that in blades with a submicrocrystalline structure strength in 20% and ductility of 50% higher than the commercially produced blades of the same alloy.
