英文摘要: The influence of 0.5 wt% nano tungsten and different mixing (turbular and magnetic mixing) on the densification, microstructure, microhardness and dilatometric properties, of tungsten materials was investigated under spark plasma sintering. The dilatometric analysis confirms that sintering process was started at 1100 °C for magnetic mixed samples but there were no sign of sintering for samples after turbular mixing. Nano tungsten and magnetic mixing increased the density of tungsten up to 98.5% at 1400 °C with the increased micro hardness value of 592 HV. The major impact after magnetic mixing is morphology changes in tungsten, development of active sites on the surface, breakdown of agglomerates and even distribution of nanoparticles throughout the bulk tungsten powder. This facilitates...
