摘要

摘要: 通过对贫铀药型罩的静破甲实验，研究了材料中微量元素对射流性能的影响。实验结果表明，贫铀中的碳含量对射流性能起着非常重要的作用，随着碳含量的增加，静破甲威力下降十分显著。最后讨论了有害微量杂质对射流造成影响的原因，指出有害杂质可以以点缺陷形式或向晶界偏聚的形式存在于材料中，它们对材料的滑移变形均起到阻碍作用，其结果造成材料延展性能下降。

Abstract: In this paper, the influence of impurities on the behavior of shaped charge jets was investigated by fire tests of depleted uranium shaped charge liner. The results of these tests indicate that impurity carbon have an important influence on the behavior of depleted uranium shaped charge jet. As the content of impurity carbon increases, the penetration depths of depleted uranium shaped charge decreased dramatically. The reason we suggest is that harmful impurities can affect the ductility of materials in different ways, such as inhibiting the dislocation movement and reducing the slip mobility, etc.
