FIELD: process engineering.
SUBSTANCE: invention relates to metal forming and may be used in hot working of intermediate blanks of titanium alloys. Blank produced by hot working after ingot heating to some 100°C - 200°C above polymorphic conversion temperature to make square cross-section blank. Straining is performed after heating the blank to 20°C - 60°C below polymorphic conversion temperature. Then, blank is recrystallised by heating to 50°C - 100°C above polymorphic conversion temperature and face upsetting with 1.3-1.4 forging reduction followed by cooling in water. Final straining is performed in several passes with single forging reduction making 1.5-2.0 after heating the blank to 20°C - 60°C below polymorphic conversion temperature. Total forging reduction in final straining makes 5.0-6.0.
EFFECT: uniform specified structure, reduced costs, power savings.
