采用拉伸性能測試和掃描電鏡觀察等方法，研究了冷拉拔變形量和時效溫度對TB9合金絲材顯微組織和力學(xué)性能的影響。結(jié)果表明：冷拉拔變形可以促進(jìn)α相的彌散析出，隨冷拉拔變形量增大，強(qiáng)度上升，塑性先升后降；經(jīng)過30%冷拉拔變形的TB9合金具有良好的綜合力學(xué)性能；在480~580
℃時效，隨時效溫度升高，α相粗化，強(qiáng)度隨之下降。
The effects of cold drawing deformation and aging
temperature on microstructures and tensile properties of TB9 titanium alloy wire
were studied using tensile test and scanning electron microscopy. It is shown
that cold drawing promotes the dispersed precipitation of α phase, and the
strength increases while the plasticity rises at first and then decreases with
rising the cold drawing deformation. Good mechanical property of TB9 alloy is
obtained after 30% cold drawing deformation. α phase is coarsened and the
strength decreases with increasing the aging temperature in the range of 480-580
℃.
