摘　　要：采用Gleeble-3500热模拟机对Ti-9.8Mo-3.9Nb-2V-3.1Al合金进行了室温~800℃范围内的热压缩变形试验,应变速率0.1 s-1.结果显示,在室温~300℃和500~800℃范围内,合金的变形抗力随温度的升高而降低,但是在300~500℃出现了异常的变形抗力随温度升高而升高的现象.最后讨论了热压缩变形行为对于试验结果的影响.Hot compressive deformation behavior of Ti-9.8Mo-3.9Nb-2V-3.1Al alloy has been studied by Gleeble-3500 Thermal Press Simulator at a series of temperatures from room temperature to 800 ℃ at a strain rate of 0.1s-1.The results showed that the compressive strength decreased with the increase of temperature between RT^300 ℃ and 500 ℃~800 ℃.However,there is an abnormal increase of the compressive strength with temperature at 300 ℃~500 ℃.The effect of precipitates on hot compressive deformation behavior has been ...
