Abstract

In order to improve the densification of W-Cu composites, mechanical milling, liquid phase activation sintering, and hot hydrostatic extrusion technologies were used. Then advanced W-35wt.% Cu composites with dispersion microstructure were fabricated. Scanning electronics microscopy and electronics probe analysis were used. The results show that the deformation processed composite with high hardness and high electrical conductivity can be achieved by mechanical milling, liquid phase activation sintering, hot hydrostatic extrusion and vacuum heat-treatment at 800°C with holding time 2 hours. The maximum specific conductance of W-35wt.% Cu composites can reach 40 m/Ω·mm and the hardness is higher than 200 HB.
