Abstract

Abstract

The microstructure and texture evolution of TB13 titanium alloy wire were investigated by multi-pass hot drawing (total deformation of 74.4%) combined with different gradient annealing processes (710-740 ℃). The results show that with the increase of hot drawing reduction, the alloy undergoes a transformation from work hardening dominated to dynamic recrystallization softening. Annealing temperature has a gradient regulation effect on the static recrystallization process. Low-temperature annealing (710-720 ℃) is mainly a recovery process, with strength maintained at 810-785 MPa, but the elongation is relatively low, only 22%-24%. Medium-high temperature annealing (730-740 ℃) achieved a good strength-plasticity match of 736-760 MPa in strength and 29%-31% in elongation through recrystallization texture reconstruction and dislocation density reset. Texture analysis shows that hot drawing induces a strong <101> // drawing direction wire texture (orientation density of 4.9), while annealing treatment achieves multi-component weak texture (<212>/<001>/<111> orientation density of 2.28-2.74) through recrystallization texture reconstruction, reducing the anisotropic characteristics.
