摘要： The W/Cu alloy powders were produced by mechanical alloying. The pre-compacted powder mixtures were reduced at various temperatures in the flowing hydrogen atmosphere. The reduced powders were explosive consolidated to fabricate dense W/Cu alloy in a cylindrical configuration/single tube set-up. The biggest density of the compact samples arrived at 98.1% T.D. The microstructure of the samples was analyzed. The sample was analyzed by EPMA and the fracture surface was investigated by SEM. The hardness and conductivity were measured. The results showed that W/Cu alloy powders could been consolidated in high density and the alloy material had high hardness and uniform structure. The physical performances is fine.
