【摘要】 利用高能球磨制取W-Cu合金化粉末,采用爆炸烧结的方法制取W-Cu合金药型罩材料。爆炸烧结样品相对致密度达到99.6%,EPMA分析表明样品内各成分及元素分布均匀。对烧结样品作XRD分析,计算其晶粒尺寸为26 nm。使用固结样品加工成W-Cu合金药型罩,显示了良好的成形性。进行无隔板的静破甲实验,并与相同工艺条件下制取的纯Cu药型罩相比,其静破甲深度提高了31.8%。

【Abstract】 The W-Cu alloy powders were prepared by high-energy ball-milling.The W-Cu alloy as liner materials was fabricated by explosive consolidation.The consolidated sample had a theoretical density of 99.6%.The sample was determined by EPMA,and the results showed that the composition and 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 forming properties.Quiet armor-piercing experiment of the W-Cu alloy liner of shaped charge without an insulating board indicates that the armor-piercing capability increases by 31.8 percent in comparison with the copper liner.
