| Abstract: |
| AlN-TiB2 composites were prepared by the hot pressed method. The effect of TiB2 content and temperature on the thermal conductivity of the composites was investigated by XRD, SEM and laser thermal conductivity apparatus. The results showed that thermal conductivity decreased gradually with the increase of TiB2 content, when w(TiB2) was 50%, thermal conductivity rate decreased from 102.9 W/(m·K) to 36.6 W/(m·K). Besides, when w(TiB2) as 10%, thermal conductivity increased gradually with the increase of temperature. The phase composition and microstructure were also studied. |
