METHOD OF MAKING WIRE FROM (α+β)-TITANIUM ALLOY FOR ADDITIVE TECHNOLOGY Russian patent published in 2021 - IPC B21B3/00 

FIELD: wire making.

SUBSTANCE: invention relates to methods for manufacturing wire from (α+β)-titanium alloys for additive technologies. The workpiece is heated and the workpiece is deformed by drawing or rolling in several passes. The deformation of the workpiece is carried out at a temperature of Т_w=(450-850)°С, at the deformation rate (25-100) m/min and the deformation degree of μ=(10-50)% per pass, while - μ=(d²_i-d²_(i+1))/d²_i×100, d_i and d_(i+1) - wire diameters before and after deformation on the i-th pass. Heating of the workpieces to this temperature is carried out by induction method using one, two or three induction heating units with a given rated power and frequency, depending on the diameter of the workpiece.

EFFECT: as a result, the wire is made in a single piece without welded joints with a homogeneous, fine-grained structure, while increasing the strength and ductility of the wire, reducing the anisotropy of mechanical properties along the length and cross-section of the wire.
