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

FIELD: technological processes.

SUBSTANCE: invention relates to methods for treating titanium alloys with a pressure 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 involves heating the workpiece and deforming the workpiece by drawing or rolling several passes. Workpiece is deformed by drawing or rolling by heating the fibers or rollers (T_f) to temperature T_f=(300–650) °C, and the 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 welds with high strength and ductility.

EFFECT: quality of the wire is increased.
