A thorough understanding of the underlying mechanisms of spark plasma sintering has been difficult to achieve due to the many processing parameters which can affect the sintering process. Conflicting results point to the various parameters. It has also been difficult to determine what effects changing a single parameter have on the final microstructure and properties of the sintered sample because many of these parameters are interdependent and often not reported. Through the detailed analysis of electrical conditions used during the SPS process of a series of samples, as well as measurements of the ac impedance response and equivalent circuit fitting of the resulting samples, it is shown that a wide array of information regarding the microstructural evolution during sintering can be revealed. The results show the unexplored potential of electrical characterization for understanding the sintering process and for elucidating the effects of processing parameters on the resulting microstructure and properties.
