Abstract

A thermomechanical process producing W-Cu composite powder with ultrafine dispersion structure was developed on the basis of the co-reduction method of W-Cu oxide powders. The produced powder was investigated by SEM, XRD, particle size distribution, oxygen contort and sintering behaviour. The results show that W-Cu oxide powders milled for 3-10 hrs are thoroughly reduced at relative low temperature and ultrafine W-Cu composite powder with high dispersion is produced by high-energy-milling the oxide powders in short time. W-Cu composite material sintered at 1200°C has relative density of 99.5% and thermal conductivity of 205 W·m^-1 ·K^-1.
