Abstract

Copper-(10-40) wt % tungsten powder blends were consolidated into cylindrical rods using the hot explosive consolidation (HEC) process. Different types of Cu-W precursor compositions with a nanometer-scale W were consolidated to near theoretical density under 1000 C. The shock wave loading intensity was about 10 GPa. The investigations showed that the combination of high temperatures below 1000 °C and a two-stage shock wave processing is beneficial to the consolidation of Cu-(10-40) % W composites, resulting in high densities, good integrity and good electrical properties. The structure and properties of the samples depended on the distribution and amount of the precursor W particles.
