| 摘 要： | 对钨合金穿甲弹和钨纤维/Zr合金金属玻璃基复合材料穿甲弹进行了靶场对比侵彻实验。穿甲弹侵彻过程中，钨合金弹芯头部形成蘑菇头、头部晶粒被径向压扁；钨纤维复合材料弹芯头部在侵彻过程中，发生了绝热剪切破坏，具有自锐行为，且在弹芯头部形成很薄的边缘层，仅在这层中金属玻璃基体破碎，钨纤维断裂，温度升高，质量消蚀。钨纤维复合材料穿甲弹的侵彻能力明显高于钨合金穿甲弹。

| Abstract: | Two kinds of the penetrating rods,which were made of tungsten heavy alloy and tungsten-fiber-reinforced Zr-based metallic glass composite material,respectively,were used to penetrate the 30CrMnMo steel target plates in the penetration experiments.In the penetration process,the tungsten heavy alloy rod head formed as a mushroom head and the grains in the head were radially compressed.But in the head of the tungsten-fiber-reinforced Zr-based metallic glass composite rod,the failure along the adiabatic shear b... |
