Abstract
Processing route has been developed with the aim to sinter refractory Al₂O₃-TiC-TiN-Mo-Ni cermet. The influence of the sintering temperature and time on relative density, surface morphologies, composition and microstructure has been studied. Grain size of sintered materials has been calculated from the XRD pattern. Al₂O₃-TiC-TiN-Mo-Ni cermet with 99% relative density and grain size of 50 nm was successfully prepared at sintering temperature of 1400°C and sintering time of 10 min. The used heating device had a high heating efficiency and simple structure. The developed process has shorter holding time and lower sintering temperature compared to the traditional processes.

Key words
microwave sintering, nanometer grain size cermet, phase transition
