摘要
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 pro-cesses(710-740 ℃).The results show that with the increase of hot drawing reduction,the alloy under-goes a transformation from work hardening dominated to dynamic recrystallization softening.Anneal-ing 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 re-crystallization 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 an-nealing treatment achieves multi-component weak texture(<212>/<001>/<111>orientation density of 2.28-2.74)through recrystallization texture reconstruction,reducing the anisotropic characteristics.关键词
