In this paper, the grain growth behavior of Ti(C,N)-based cermet, including the microstructure evolution and sintering kinetics in the sintering process at different temperatures for different holding time, was studied experimentally and theoretically. A comprehensive grain growth model for Ti(C,N)-based cermet was established based on the experimental data. Furthermore, different influencing factors of microstructure evolution during sintering for Ti(C,N)-based cermet were investigated systematically by a scanning electron microscope. The results showed that the sintering temperature and holding time have a significant effect on the microstructure evolution of Ti(C,N)-based cermet. The grain growth rate was the fastest at the temperature range of 1300°C to 1400°C. The grain growth rate was reduced slightly at higher temperatures. A comprehensive sintering kinetics model of Ti(C,N)-based cermet during the sintering process was obtained based on the experimental results via nonlinear regression method.
