| 摘要: |
| 本文研究了 NICALON SiC束丝纤维增强铝预制丝在15-400℃ 温度区间内的热膨胀特性。研究表明预制丝两次热循环后得到的膨胀曲线不一致，该曲线在 15-400℃范围的平均热膨胀系数分别为 3.2×10-6℃-1、4.1×10-6℃-1。本文对预制丝的热膨胀行为进行了理论分析和探讨，计算值和实验值较为符合。 |

| Abstract: |
| The thermal expansion property of NICALON Sic multifilaments reinforced Al preformed wire has been measured in the range of 15-400℃. The thermal expansion processes are made two times for one sample and the expansion curves of the first and second time are different. The averaged thermal expansion coefficients are respectively 3.2×10-6℃-1 and 4.1×10-6℃-1 for the first and second thermal cxpansion processes. The thermal expansion performance has been analysed theoretically and the calculated values are approximately in agreement with the experimental data. |
