In order to explore the compacting process of refractory metals and copper powder,the preparation method of spray pyrolysis—wet ball?mixing—liquid phase sintering of fine grain W?Cu alloy was put forward. The W?Cu alloy composite material with high density and nano grain was prepared through the repeated tests. The density of EFP liner prepared with this material can achieve 99.8% of theoretical value and the tensile strength reaches 320 MPa after two?step forging processes. The results show that the fine grain W?Cu alloy material has good comprehensive performance,and some formability,which is helpful to improve the penetration capacity of W?Cu alloy liner.
