分别选用不同的固溶温度、固溶冷却方式和时效保温时间对Ti-8V-8Cr-2Zr-3Al合金丝材进行热处理，研究了热处理制度对丝材室温拉伸性能及金相显微组织的影响。结果表明：固溶处理温度在740～820℃范围内，力学性能及显微组织对温度不敏感，固溶温度继续提高时，材料晶粒明显变大，强度降低，塑性下降；固溶温度为740℃，分别以水淬、空冷方式冷却，材料的组织、性能无明显变化，以炉冷方式冷却，强度提高，塑性下降。眼镜架用Ti-8V-8Cr-2Zr-3Al合金丝材较为理想的热处理工艺为740℃×10 min/AC＋550℃×（4～6）h/AC，经该工艺处理后，材料的抗拉强度约1120 MPa，延伸率大于12％，能够满足用户要求。
The effect of heat treatment on the tensile properties at room temperature and microstructure of Ti -8 V-8Cr-2Zr-3Al wire were investigated by adopting different solution temperature , cooling method and aging temperature respectively .The results show that the microstructure and mechanical properties do not have significant change when the solution temperature is 740~820 ℃.When the solution temperature is above 820 ℃, grain size enlarges obviously while the strength and ductility decrease . Under the solution temperature of 740 ℃, microstructure and tensile properties do not change significantly by AC or WC , but the strength increases while the ductility decreases by FC.The optimum heat treatment process for Ti-8V-8Cr-2Zr-3Al wire is 740 ℃×10 min/AC+550 ℃×(4~6) h/AC, the tensile strength is 1 120 MPa and the elongation is above 12% after annealing, which could meet user’ s requirements.
