Sinterability of carbide-nitride phases of titanium in high pressure conditions
Abstract Results of research in the field of sintering titanium carbonitride phases, its compactibility in high pressure (up to 8.0±0.2 GPa) and high temperature (1700±50 K) conditions. Mixed powders of TiC, TiN, or mixed phases Ti(C,N) type were tested in the order of increasing nitrogen content. All the samples reached density of 96–99% and their hardness depends on the nitrogen content and on the structure of the sintered powders. The applied sintering conditions did not cause any distinct growth of the mean grain of the sintered compact, nor any lost of nitrogen content. Electron Microprobe Analysis and X-ray diffraction studies proved, that with the above sintering parameters TiC and TiN partial homogenizing process occurs; powders of carbonitride phases are less active.
