Abstract: During Spark Plasma Sintering (SPS), electric current passing through the sample can cause specific effects not observed in the absence of current. We present microstructural evidence of the formation of melt at the inter-particle contacts during SPS of mechanically milled Ti–C–3Cu mixtures transforming into TiC–Cu composites. The shape of the composite particles acquired after ball milling is related to inter-particle melting during SPS. Particles with higher width/length ratios show a greater tendency to melt at the contacts. The reinforcing effect of TiC inclusions plays a key role in preserving the initial inter-particle contact areas small, as plastic flow at high temperatures was inhibited.
