FIELD: metallurgy; mechanical engineering; aircraft engine manufacture; medicine.
SUBSTANCE: proposed method includes intensive plastic deformation of blank in crossing vertical and horizontal channels at temperature of 600°C at stored logarithmic degree of deformation no less than 2. Heat treatment performed before intensive plastic deformation includes hardening from temperature of polymorphous transformation of minus 10°C in water and high-temperature aging at temperature of 675-700°C continued for 4 hours at cooling in air; after intensive plastic deformation, blank is subjected to extrusion performed in several passes at temperature of 300°C and drawing coefficient no less than 1.2.
EFFECT: improved strength characteristics (ultimate strength, yield point, fatigue range); enhanced homogeneity at retained satisfactory ductility.
