Effect of compaction pressure on microstructure and properties of copper-based composite prepared by mechanical Aaloying and powder metallurgy

this study, copper-tungsten carbide composite was produced by mechanical alloying
and powder metallurgy. The compaction pressures were varied from 100 to 600 MPa for
observation on microstructure and properties of the composite. The result showed the microstructure
was densified with the increased of compaction pressure. Within compaction pressure no fracturing
was occurred. Increasing compaction pressure increased the density, hardness and electrical
conductivity of the composite which related to the reduced of porosity area.
