The hot-stage of a scanning electron microscope has been used to observe liquid-phase sintering in the system iron-copper. The densification behaviour of compacts of Fe and Cu particles were determined. The influence of particle size of both components and the amount of liquid phase developed were investigated. In samples with about 20 vol % liquid phase, the densification kinetics as observed by direct observation shows that no rearrangement takes place. In samples with 40 vol % liquid phase and particle sizes of 10 to 20 µm, some rearrangement was observed. |
