摘要：

A mechanism of self-propagating high-temperature synthesis (SHS) of TiC-Cu cermet was studied by means of a combustion front quenching method. Microstructural evolution in the quenched sample was observed using a scanning electron microscope (SEM) with energy dispersive X-ray (EDX) spectrometry, and the combustion temperature were measured. The results showed that the combustion reaction started with a local formation of a Ti-Cu liquid solution and could be described with a dissolution-precipitation mechanism, namely, Ti, Cu and C particles dissolved into the Ti-Cu solution and TiC particles precipitated in the saturated Ti-Cu-C liquid solution. The local formation of the Ti-Cu solution resulted from a solid diffusion between the Ti and Cu particles.
