测试了ＴＡ５钛合金在Ａ区８００～９５０℃、ε＝１０￣（－１）ｓ￣（－１）条件下的压缩真应力－真应变曲线，结果表明：其曲线为动态回复型，动态回复是主要的变形机制。对所得曲线进行了数学分析，提出了流变应力模型。
The true stress-strain curves of TA5 titanium alloy under the conditions of 800-950 ℃ and ε = 10 ~ (-1) s ~ (-1) in zone A were tested. The results show that the curves of dynamic compression and dynamic recovery Is the main deformation mechanism. Mathematical analysis of the resulting curve, put forward the flow stress model.
