摘要：
The submicron powder mixtures of TiC-TiN-WC-Mo-C-Ni sintered at 1400℃ or below in vacuum were studied by X-ray diffration （XRD）, scanning electron microscopy （SEM） and transmission electron microscopy （TEM） analyses. The results showed that Mo2C fOrmed at 800℃ or below. Both WC and Mo2C disappeared at 1200 ℃, and TiN disappeared at 1250℃. In addihon, the variahons of lanice constans of the htanium carbonitride and nickel binder phase with sintering temperature were experimentally obtained, and the reason was analyzed.
