摘　　要：首先通过高能球磨法制取纳米W-Cu粉末,再对混合粉末进行爆炸压实制取W-Cu纳米合金药型罩材料,压实样品致密度达到了99.6%T.D。对样品进行电子探针分析(EPMA),显示样品内部元素及成分基本分布均匀。对样品进行XRD实验,计算结果表明W晶粒尺寸基本分布在26 nm。将W-Cu合金样品切割成药型罩形状,显示了良好的机械加工性能。最后对W-Cu合金药型罩进行无隔板静破甲实验,并与同尺寸的铜金属罩比较,表明W-Cu合金药型罩的破甲能力相对提高了30%以上。The nanostructured W-Cu powder was prepared by high-energy ball-milling. The W-Cu alloy as liner materials wasfabricated by the dynamic consolidation technique. The density of the consolidated sample was 99.6% T.D. The sample wasdetermined by EPMA, and the results show that the composition and the distribution of the elements were uniform. The samplewas 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 aninsulating board indicates that the armor-piercing capability increases by more than 30% in comparison with the copper liner.
