The hot deformation behavior of beta C titanium alloy in β phase field was investigated by isothermal compression tests on a Gleeble-3800 thermomechanical simulator. The constitutive equation describing the hot deformation behavior was obtained and a processing map was established at the true strain of 0.7. The microstructure was characterized by optical microscopy (OM), scanning electron microscopy (SEM) and electron back-scattered diffraction (EBSD) technique. The results show that the flow stress increases with increasing strain rates, and decreases with increasing experimental temperatures. The calculated apparent activation energy (167 kJ/mol) is close to that of self-diffusion in β titanium. The processing map and microstructure observation exhibit a dynamic recrystallization domain in the temperature range of 900-1000 °C and strain rate range of 0.1-1 s~(-1). An instability region exists when the strain rate is higher than 1.7 s~(-1). The microstructure of beta C titanium alloy can be optimized by proper heat treatments after the deformation in the dynamic recrystallization domain. |

利用Gleeble-3800热模拟试验机对beta C钛合金进行等温压缩试验,研究其在β相区的热变形行为。得到了描述热变形行为的本构方程,获得了真应变为0.7时的加工图。采用光学显微镜、扫描电子显微镜和电子背散射技术对变形显微组织进行表征。结果表明:流变应力随着应变速率加快而增大,随着试验温度的升高而减小。计算得到的表观激活能为167 kJ/mol,接近β钛的自扩散激活能。加工图和显微组织观察表明在温度为900~1000 °C和变形速率为0.1~1 s~(-1)的区间存在一个动态再结晶区。加工图显示,当变形速率大于1.7 s~(-1)时,beta C钛合金发生不稳定变形。Beta C钛合金在动态再结晶区变形后,经合适的热处理,显微组织可以被优化。 |
