| 摘 要： | 利用Hopkinson压杆技术对V-5Cr-5Ti合金动态压缩力学性能进行了实验测试,获得了不同应变率下V-5Cr-5Ti合金的压缩应力—应变曲线,结果显示V-5Cr-5Ti合金具有较强的应变率敏感性。根据实验结果,确定了描述V-5Cr-5Ti合金常温动态性能本构参数,并将实验结果与计算结果进行了比较,两者吻合较好。

| Abstract: | Split-Hopkinson-Pressure Bar（SHPB） technique had been used to investigate the basic dynamic compression mechanical properties of V-5Cr-5Ti alloy.The stress-strain curves for different strain rates have been obtained,and the curves show that V-5Cr-5Ti alloy exhibits definite strain-rate sensitivity.Based on the results,constitutive parameters that describe the dynamic properties of V-5Cr-5Ti alloy at room temperature have been determined.The experimental results and the calculation results match well. |
