FIELD: metallurgy.
SUBSTANCE: invention relates to metallurgy, specifically to a method of thermomechanical treatment of titanium or titanium alloy. Method comprises multiaxial forging with high rate of deformation and temperature control. Temperature of forging workpiece is in a range from temperature which is 100 °F (55.6 °C) below beta-transition temperature of workpiece material to a temperature 700°F (388.9 °C) below beta-transition temperature of workpiece material, and deformation rate used in process of forging at a press is in a range from 0.2 s-1 to 0.8 s-1.
EFFECT: improved mechanical properties due to grinding of alloy microstructure.
