Abstract:
In the present work, the evidence of the melt formation at the contacts between composite TiC-Cu particles
formed by high-energy ball milling was found in the microstructure of compacts obtained by spark plasma
sintering at real temperatures of the sample of 725–925 ◦C. The voltage drop associated with a contact that could
have been heated up to the melting point of copper was calculated to be much higher than the voltage across the
whole sample during SPS. As the formation of melt could not be attributed to simple overheating of small crosssectional area contacts (bridges), another explanation of the observed effect was sought. A mechanism based on
the micro-arc formation was proposed to explain the observed melt formation in the sintered composites.
