- W and W alloys containing 0.5 wt% Y2O3, x wt% Ti and (x wt% Ti + 0.5 wt% Y2O3) have been prepared, x = 2 or 4. Elemental powders were blended or ball milled, canned, degassed and finally consolidated by a two-stage HIP process under a pressure of 195 MPa. It is found that Ti addition favours the densification attaining a fully dense material. XRD, SEM and EDX analyses of the material with Ti addition reveal the formation of a microstructure consisting of tungsten particles embedded in a W-Ti matrix. The microhardness of these materials increased noticeably with the titanium content.
