FIELD: metallurgy.
SUBSTANCE: forgings manufacturing method from titanium alloys includes extrusion of billet under isothermal conditions at the same temperature of heating the billet and die and subsequent isothermal forging of the extruded billet. The extrusion and isothermal forging is performed at the heating temperature of the die and billet 800-830 °C±40 °C at average strain rate not more than 0.3 mm/s.
EFFECT: reduce of alloy deformation resistance and increase of dimensional stability of dies, manufacturing of blade forgings with a fine-grained structure.
