摘要:为了研究Cu含量对Cu-Ni-Al反应射流侵彻性能的影响，采用粉末冶金法制备了Cu含量为30%、50%和70%的Cu-Ni-Al粉末药型罩并对其进行静破甲试验。结果表明：随着Cu含量增加，Cu-Ni-Al反应射流的穿深增大，平均扩孔孔径减小，侵彻孔容先增大后减小，在50%Cu时达到最大值，相比30%Cu和70%Cu时孔容分别提升了5%和15%；聚能射流侵彻阶段孔径衰减随着Cu含量的增加而减小。研究结果可为评估反应材料药型罩聚能装药战斗部的毁伤效应提供参考。
Abstract:In order to study the effect of Cu content on the penetration performance of Cu-Ni-Al reactive jet, the Cu-Ni-Al powder liners with Cu content of 30%, 50% and 70% were prepared by powder metallurgy method, and the static armor test was carried out. The results show that with the increase of Cu content, the penetration depth of the Cu-Ni-Al reaction jet increases gradually, the average entrance diameter decreases gradually, and the penetration volume increases first and then decreases. The maximum value is reached at 50%Cu, and the pore volume increases by 5% and 15% respectively compared with that of 30%Cu and 70%Cu. The entrance diameter attenuation of shaped charge jet decreases with the increase of Cu content. The research results can provide a certain reference for evaluating the damage effect of the reactive material liners shaped charge warhead.
