| 摘 要： | 采用粉末冶金法制备了TiC-10%Mo-20%Ni金属陶瓷,研究了不同过程控制剂对组织性能的影响,采用Rietveld全谱拟合法对X射线衍射图谱进行分析,金属Mo和Ni与TiC发生固溶反应,形成了典型的芯-环结构,选用正己烷为过程控制剂时,在1 450℃烧结金属陶瓷的硬度最高达到1 432HV30,断裂韧性为10.47 MPa·m~(1/2)。

| Abstract: | TiC-10% Mo-20%Ni cermet was prepared by powder metallurgy. The effect of different process control agents on its microstructure and properties were studied. Its X-ray diffraction patterns were analyzed by Rietveld full spectrum fitting. The solid solution reaction of Mo and Ni to TiC resulted in the formation of a typical core-ring structure. With n-hexane as the process control agent, the cermet sintered at 1 450℃ exhibits maximum hardness of 1 432HV30 and fracture toughness of 10.47 MPa·m/2. |
