N2 - Microstructural evolution and grain growth kinetics of nanocrystalline titanium nitride powders were investigated, when being isothermally annealed using microwave and conventional sintering. The results show that, microwave sintering of nanocrystalline TiN results in fine microstructure ~220 nm, as compared to the conventional sintering 335 nm. Grain growth process during microwave sintering occurred mainly by mechanism of grain-boundary diffusion with an activation energy of 230 kJ mol-1, while in case of conventional sintering, the mechanism of volume diffusion was assumed with the activation energy of 390 kJ mol-1.
