摘　　要：测试了Ti-10V-2Fe-3Al合金在β区850℃～950℃、ε=5×10^(-3)～10s^(-1)条件下的压缩真应力-真应变曲线。研究了变形组织。结果表明:在850℃～950℃、ε=10^(-1)～10s^(-1)范围内变形,动态回复是主要软化机制,其σ-ε曲线为动态回复型,变形后的组织为拉长晶粒。对所得的σ-ε曲线进行了数学分析,得出了流变应力模型。The compressive true stress vs.true strain curves of Ti-10V-2Fe-3Al alloy have been measured in β phase region at 850℃~950℃×10-ss-1~10s-1.The results show that the soft mechanism is mainly dynamic recovery when the specimen is deformed in the range of T = 850℃~950℃ and e = 10-1s-1~10s-1, the -e curves show the shape of the dynamic recovery and the deformed grain is lengthened. The mathematical model of flow stress has been proposed on the basis of mathematical analysis.
