FIELD: metallurgy.
SUBSTANCE: method for obtaining high-strength wire from (α+β)-titanium-based martensite alloy involves obtaining of ingot, its hot deformation so that workpiece for drawing is obtained; drawing at room temperature till final size is obtained, and final heat treatment. After heat treatment is completed, the obtained workpieces are annealed in the air and machined; drawing is performed for many times with intermediate annealings in the air environment; at that, the machining is performed after the first drawing pass, and final heat treatment is performed in the air environment during 60-180 minutes at temperature of (0.5÷0.7)TSL °C with further cooling to room temperature.
EFFECT: increasing ultimate tensile strength at maintaining the high level of relative elongation due to uniformity of the structure throughout the length and section of wire.
