| 摘 要： | 首先测试了6082铝合金的静态拉伸和压缩力学性能;然后利用分离式霍普金森压杆试验设备测定了6082铝合金试件在经过不同条件冷作硬化后4组试件的动态力学性能,利用二波法处理试验数据得出材料的动态应力-应变曲线。试验结果表明：动态冲击下材料的屈服极限比静态压缩时有了大幅下降;在含有塑性变形试件的动态冲击试验中,试件的塑性变形越大,其屈服极限越高。

| Abstract: | Static tensile and compressive mechanical properties of 6082 aluminum alloy were measured.The results show that yield limit of the specimen under the dynamic impact is far less than that under the static compressive load;the more the plastic deformation the specimen has,the higher the yield limit is. |
