Notes:
An infiltration technique using W-Cu composite powder has been developed to enhancemicrostructural uniformity of W-Cu pseudo-alloy. W-Cu composite powder, manufactured byreduction from WO3 and CuO powder mixtures, were blended with W powder and then cold isostaticallypressed into a cylindrical bar under 150 MPa. The pressed samples were pre-sintered at1300 oC for 1 hour under hydrogen to make a skeleton structure. This skeleton structure was morehomogeneous than that formed by using W and Cu powder mixtures. The skeleton structures wereinfiltrated with Cu under hydrogen atmosphere. The infiltrated W-Cu pseudo-alloy showedhomogeneous microstructure without Cu rich region
