中文摘要：

采用W／WC多孔预制体中低温熔渗Zr2Cu合金的方法成功制备了W／ZrC复合材料。结果表明：与传统粉末冶金方法相比，制备温度降低了500℃左右。复合材料的组织均匀，致密度较高；抗弯强度和弹性模量分别可达600MPa和360GPa：断裂韧性达11．0MPa·m^1/2，比纯ZrC的断裂韧性提高了4倍。

英文摘要：

In order to solve the problem of high sintering temperature and reduce the machining costs, the W/ZrC composites were successfully fabricated by the reactive melt penetration （RMP） of Zr2Cu alloy into the porous W/WC presinters at 1400 ℃ for 2 h. Comparing with the conventional powder metallurgy （PM）, this process can reduce the fabrication temperature for about 500℃. The W/ZrC composites fabricated by this process have homogeneous microstructure and higher relative density with the maximal flexural strength and elastic modulus of 600 MPa and 360 GPa, respectively, and the maximal fracture toughness of 11 MPa·m1/2, four times higher than that of pure ZrC.
