| 摘 要： | 选用WC、（W,Ti）C、TaC和Co粉配制WC-16TiC-4TaC-9Co合金混合料,经球磨后压制压坯,在1 410℃、1 430℃和1 450℃温度下真空烧结.测试烧结试样的性能,采用扫描电子显微镜（SEM）观察其微观形貌.结果表明：随着烧结温度升高,合金晶粒尺寸明显长大.1 450℃真空烧结的试样综合性能较好,WC平均尺寸为0.7μm,（W,Ti,Ta）C平均尺寸为3μm.

| Abstract: | WC-16TiC-4TaC-9Co cemented carbides alloy mixture were made of WC、TaC、（W,Ti） C and Co powder by ball milling.The sample was pressed and vacuum sintering at 1 410 ℃ 、1 430 ℃ and 1 450 ℃.The properties of the sintering sample were tested and the microstructure was observed by SEM.The results show that： with the increase of the sintering temperature,grain size of the alloy obviously grew.The comprehensive properties of samples at 1 450 ℃ sintering in vacuum is better,the average WC size is 0.7 μm,（W,Ti,Ta） C average size of 3 μm. |
