Abstract

In this study we used the SPS spark plasma sintering method (hereafter SPS) with single Mo powder, a mixed powder and an added Ni powder which was thought to promote sintering of the Mo powder. SPS is a very effective sintering method for Mo powder sintering too, because density remarkably improved when using the lower sintering temperature. But, grain particles in the microstructure grew to a large size as sintering progressed. This sintering process is significantly time dependent, while surface and boundary diffusion proceeds quickly and soon comes to an end. The density of Mo mixture added Ni powder increased more in lower sintering temperatures than the single Mo powder on SPS. However, the decrease of activation energy on densification for sintering of Mo mixture added Ni powder is smaller than that of Mo powder.
