FIELD: metallurgy.
SUBSTANCE: compressor blades are made out of high strength titanium alloy BT6 based on eutectoid alloying system. Hot deformation by gas forming using the superplasticity effect is performed at temperature from 870°C to 1000°C and deformation rate 10-4 s-1. Finished compressor blades are heat treated at temperature from 870 to 950°C with holding during homogenization and ageing from 450 to 600°C.
EFFECT: invention ensures the process optimization upon improvement of the blades mechanical properties, namely, strength, high temperature strength, fracture toughness.
