Joint effect of Zr and Cu on the properties of new powder metallurgy

In this study new Ti–Zr–Cu alloys were designed to be manufactured via the classical PM route using the blended elemental approach. The data of the physical properties shown in Fig. 1 indicate that the Ti–Zr–Cu alloys have higher density in comparison to Ti, which is expected as both Zr and Cu have higher density than Ti. From the variation of the relative green compact density as a function of the amount of Zr or Cu, the compressibility of the Ti–Zr–Cu powder blends monotonically decreases.

In this study the joint of effect of Zr and Cu in Ti–Zr–Cu alloys produced via the classical powder metallurgy route of cold press and sinter was analysed. From it, it can be concluded that the addition of the selected Zr and Cu powders to Ti decreases the compressibility due to the unfavourable powder morphology but increases the sinterability. In particular, Cu boosts whereas Zr hinders densification, respectively. This leads to the achievement of higher relative density values compared to..,
