Explosive consolidation of W-Cu alloy as liner materials and its performance

WANG Zhan-lei,LI Xiao-jie,ZHANG Cheng-jiao, YI Cai-hong,WANG Hai-tao,SUN Wei(Department of Engineering Mechanics,Dalian University of Technology, Dalian 116024,Liaoning,China)  
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.
