The mechanism of material transport during the process of liquid-phase sintering was studied in a model experiment, in which twisted iron wires were sintered in molten silver and the neck growth between the wires was measured as a function of time and temperature.
In the sintering with liquid silver the centers of wires did not approach because no grain boundaries were formed in the neck area even though an appreciable neck growth was observed. The rate of neck growth in the sintering with liquid silver was higher than the case without the liquid, and this was explained as a cumulative effect of two types of mechanisms of material transport, which are the solution-diffusion-precipitation and the volume diffusion. Contributions of the latter mechanism to the neck growth were less than those of the former.
