| 摘 要： | 通过对一种新型锆钛合金在室温下的准静态压缩和不同温度下的动态压缩实验,发现该合金在准静态和动态压缩条件下均具有良好的强度和塑性,且随着应变速率的增加和温度的降低,合金强度升高,塑性下降.基于Johnson-Cook模型,建立了该锆钛合金动态压缩下的本构关系.

| Abstract: | Zirconium based alloy is a new type structural material with high specific strength and good comprehensive properties.In this article,quasi-static compression at room temperature and dynamic compression under various temperatures were performed to a new zirconium-titanium alloy.It was found that this alloy showed good strength and plasticity,and the strength increased and plasticity decreased with increasing strain rate or decreasing temperature.A constitutive model under dynamic compression was established based on Johnson-Cook model,and accorded well with experimental results. |
