METHOD FOR MANUFACTURE OF (α+β)-TITANIUM ALLOY WIRE FOR ADDITIVE TECHNOLOGY Russian patent published in 2019 - IPC B21B3/00 C22F1/18 B21C23/08 

FIELD: technological processes.

SUBSTANCE: invention relates to methods for treating titanium alloys and can be used in the manufacture of wire from (α+β)-titanium alloy for additive technology. Method for manufacturing wire from (α+β)-titanium alloys for additive technologies includes heating and deformation of the preform by drawing or rolling in several passes. Workpieces are deformed by drawing or rolling by heating preforms (T_p) to temperature T_p=300–635 °C. Deformation velocity (V) of the workpiece is selected at each pass, depending on the diameter (d) of the workpiece: V=(2–10) m/min for the diameter d=(from 8.0 to 7.0) mm, V=(10–15) m/min for the diameter d=(from less than 7.0 to 5.0) mm, V=(15–20) m/min for the diameter d=(from less than 5.0 to 4.0) mm, V=(20–30) m/min for the diameter d=(from less than 4.0 to 3.0) mm, V=(30–40) m/min for the diameter d=(from less than 3.0 to 2.0) mm, V=(40–60) m/min for the diameter d=(from less than 2.0 to 1.6) mm. Obtain wire with a single piece without welded joints with high strength, ductility and low anisotropy of mechanical properties along the length of the wire.

EFFECT: quality of the wire is increased.
