利用高能球磨和热压烧结方法制备TiC/W基复合材料,通过微观形貌、相对密度、显微硬度、杨氏模量和抗弯强度等表征方法分析了TiC弥散增强钨基复合材料的效果。结果发现,TiC弥散相有效地抑制了W晶粒的长大,断裂模式转为穿晶断裂,有效增强了W基合金材料的性能,特别是纳米TiC质量分数为1%时,增强效果较显著。与纳米TiC相比,微米TiC增强效果不明显。 TiC / W matrix composites were prepared by high-energy ball milling and hot-pressing sintering. The effects of TiC dispersion strengthening tungsten matrix composites were analyzed by means of characterization of morphology, relative density, microhardness, Young’s modulus and flexural strength . The results show that TiC dispersed phase effectively inhibits the growth of W grains and transforms the rupture mode into transgranular rupture and effectively enhances the properties of W based alloy materials. Especially when the mass fraction of nano-TiC is 1%, the enhancement effect is more significant . Compared with the nano-TiC, micron TiC enhancement effect is not obvious.
