FIELD: mechanical engineering; aircraft engine manufacture and medicine.
SUBSTANCE: proposed method consists in thermo-mechanical treatment accompanied by change in mechanical properties of material. Proposed method includes intensive plastic deformation of blank in crossing vertical and horizontal channels at temperature of 600°C and stored logarithmic degree of deformation no less than 2. After intensive plastic deformation in crossing channels, blank is subjected to extrusion by several passes at temperature of 300°C and drawing coefficient no less than 1,2.
EFFECT: enhanced strength characteristics of titanium alloys (ultimate strength, yield point, fatigue range) at retained satisfactory ductility.
