| 中文摘要: |
| 采用热压烧结工艺制备了AlN-TiC复相材料.通过激光导热仪,研究了TiC含量对材料导热性能的影响.结果表明:随着TiC的质量分数的增加,复相材料的热导率逐渐下降,当TiC的质量分数增至50t%时,热导率由102.9 W/(m·K)下降到46.6 W/(m·K),并对AlN-TiC的相组成和显微结构进行了观察分析. |

| AlN-TiC composites with microwave attenuation characteristics were made by hot pressed method.The effect of the content of TiC on the composites was investigated by laser thermal conductivity apparatus.The results show that with the increasing of TiC content,thermal conductivity rate decreases gradually,when the w(TiC) come to 50t%,thermal conductivity rate decreases from 102.9 W/(m·K) to 46.6 W/(m·K).In addition,the phase composition and microstructure were also studied. |
