Abstract

The effects of activated sintering technology of H2 atmosphere sintering on the microstructure and properties of W-15Cu alloy using ultrafine W-15Cu composite powder fabricated by spray drying & calcining-continuous reduction technology were investigated. The experimental results showed that W-15Cu alloy, consolidated by activated sintering technology of H2 atmosphere sintering for 1 h at 1300 °C, with 98.5 % relative density, transverse rupture strength 1218 MPa, Vickers hardness HV0.5 378, average grain size about 1.2 μm and thermal conductivity 192 W/m·K, was obtained. In comparison to the normal sintering process, activated sintering process to W-15Cu alloy could be achieved at lower sintering temperature. Furthermore, better properties in activated sintered compacts were obtained, and activated sintering process resulted in finer microstructure and excellent properties.
