    摘要:

    首先通過高能球磨法制取納米W-Cu粉末，再對混合粉末進行爆炸壓實制取W-Cu納米合金藥型罩材料，壓實樣品致密度達到了99.6% T.D。對樣品進行電子探針分析（EPMA），顯示樣品內(nèi)部元素及成分基本分布均勻。對樣品進行XRD實驗，計算結(jié)果表明W晶粒尺寸基本分布在26 nm。將W-Cu合金樣品切割成藥型罩形狀，顯示了良好的機械加工性能。最后對W-Cu合金藥型罩進行無隔板靜破甲實驗，并與同尺寸的銅金屬罩比較，表明W-Cu合金藥型罩的破甲能力相對提高了30%以上

    Abstract:

    The nanostructured W-Cu powder was prepared by high-energy ball-milling. The W-Cu alloy as liner materials was fabricated by the dynamic consolidation technique. The density of the consolidated sample was 99.6% T.D. The sample was determined by EPMA, and the results show that the composition and the distribution of the elements were uniform. The sample was analyzed by XRD, and the W crystalline sizes were measured as 26 nm. The sample was machined into W-Cu alloy liners, showing good properties of machinability. The armor-piercing experiment of the W-Cu alloy liner of shaped charge without an insulating board indicates that the armor-piercing capability increases by more than 30% in comparison with the copper liner
