FIELD: metallurgy.
SUBSTANCE: invention refers to heat treatment of high-strength (α+β)-titanium alloys and can be used in aerospace equipment during manufacture of power parts of structures. Heat treatment method of high-strength (α+β)-titanium alloys is proposed. Heating is performed over temperature of polymorphic transformation, exposure at that temperature, cooling to temperature of 680-630°C at the rate of not less than 18°C/min with further exposure during 1-3 h, heating to temperature of 720-780°C and exposure at that temperature during 2-3 h, cooling to temperature of 520-480°C at the rate of not less than 12°C/min. Then, heating is performed to ageing temperature, exposure at that temperature and cooling in the air. Alloys are characterised with high mechanical properties.
EFFECT: improving reliability of products of aerospace equipment owing to achieving higher level of mechanical properties.
