Densification of Mo Alloys at 1473 K by Adding Ni-Cu Solid Solution

Keywords： Mo alloys

Mo is difficult to sinter densely at a relatively low temperature due to its high melting point. In the present paper, by adding different weight contents of Ni and Cu additives, Mo alloys have been densified at 1473 K for an hour by hot-pressing method, and the optimum contents of Cu and Ni additives have been acquired: when the contents of Ni and Cu are 3 and 2 wt pct respectively, the relative density of the sample reaches the maximum value. It was found that when the Ni-Cu solid solution was added into Mo alloys, the achieved density is higher than the case of Ni and Cu additives. The experimental results indicate that, Ni and Cu play different roles in the process of sintering, the Ni-Cu solid solution has the same function as Ni and Cu additives in the course of sintering Mo alloys, It shows more activating sintering feature for Mo than the Ni and Cu additives.
