中文摘要:
      对不同状态(热变形态、热变形+T5 态和热变形+T6 态)ZK60 镁合金靶板进行了弹丸高速冲击(500 m/ s)变形实验研究。结果表明,高速弹击实验后,在靶材弹孔背面出现了白亮的剪切唇,说明ZK60 合金靶材具有较好的塑性,在高速弹击情况下,吸能性较好,具有较好的抗弹性。热变形+T5 态ZK60 镁合金靶板抗弹性较好,弹坑周围几乎不出现裂纹;通过线性回归分析,建立了弹坑深度与靶板材料力学性能之间的关系式,说明了当ZK60 镁合金综合力学性能都较高时,材料就可获得优异的抗弹性。
英文摘要:
      The impact process and failure characteristic ofdifferent states ZK60 alloy (hot deformation, defoprmation+ T5, deformation+T6) under high speed impact by steel bullet have been innestigated. The results showsthat ZK60 alloy has better defensible performance because of shear ship appears in the shot hole back of target plate. The defensible performance of hot deformed + T5 state ZK60 alloy is better. The cracks hardly appear around the crater. The relation between shear depth and mechanical properties of target plate material is established by linear regression equation. The relation states shows that only whencomprehensive mechanical properties of ZK60 alloy could reach the most ideal state, the material can obtain excellent defensible performance.
