METHOD OF MAKING WIRE FROM (α+β)-TITANIUM ALLOY FOR ADDITIVE TECHNOLOGY WITH CONTROL OF TEMPERATURE TOLERANCE AND HIGH DEGREE OF DEFORMATION Russian patent published in 2019 - IPC B21C23/08 B21F99/00 B21B3/00 C22F1/18

Abstract RU 2690905 C1

FIELD: metallurgy.

SUBSTANCE: invention relates to methods of processing titanium alloys with pressure containing aluminum, vanadium, and can be used in making wire from (α+β)-titanium alloy by hot deformation used for additive technology. Proposed method comprises billet heating and deformation by drawing or rolling. Billet is heated by induction method using one, two or three induction heating devices depending on its diameter, and workpiece is deformed at temperature T_s= (450–850) °C with deformation temperature tolerance control equal to ±10 °C, at workpiece deformation degree μ = (10–50) % per one pass. Parameters of induction heating settings are given depending on billet diameter.

EFFECT: reduced duration of full cycle of wire production, increased strength and plasticity of wire.
