| 摘 要： | 研究了几种不同热处理工艺对Ti80钛合金棒材显微组织和室温力学性能的影响。结果表明:随着热处理温度的升高,显微组织由等轴组织变为魏氏组织;后期需要进行塑性成形时,适宜选择850 ℃保温80 min后空冷的工艺后热处理;经750 ℃保温80 min后空冷的热处理工艺,Ti80钛合金棒材的强度与塑性匹配较好。

| Abstract: | Effects of different heat treatment process on microstructure and room temperature mechanical properties of the Ti80 titanium alloy bars were studied. The results show that with the increase of heat treatment temperature, the microstructure of the Ti80 titanium alloy changes from equiaxed structure to widmanstatite structure. When plastic forming is required in the later period, it is appropriate to choose the heat treatment process of air-cooling after heating at 850 ℃ for 80 min. After the heat treatment process of heating at 750 ℃ for 80 min and then air-cooling, the strength and plasticity of the Ti80 titanium alloy bars match well. |
