FIELD: metallurgy. ^ SUBSTANCE: method for obtaining high-strength wire from (+)-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 (0.50.7)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. ^ 1 tbl, 2 ex |
