用扫描电子显微镜热台观察了碳化钨-钴体系的液相烧结。致密化行为和机制的第一，快速阶段的烧结已被确定;颗粒尺寸和液相量的影响进行了研究。在所有样品中的致密化动力学是重排过程，直接观察证实了这一结果。
The hot-stage of a scanning electron microscope has been used to observe liquid-phase sintering in the system tungsten carbide-cobalt. Densification behaviour and the mechanism for the first, fast stage of sintering have been determined; the influence of particle size and the amount of liquid phase has been investigated. In all samples the densification kinetics is that of a rearrangement process; direct observation confirmed this result.
