研究了经峰时效（Ｔ５）及过时效（Ｔ５＋３００℃）处理的莫莱石短纤维增强ＺＬ１０７复合材料在３００℃时的拉一拉循环蠕变的行为．实验结果表明：两种热处理状态下，复合材料都显示出循环蠕变减速现象峰时效状态下，循环蠕变与静态蠕变相比表现出低的表观激活能，非热空位机制作用较大；而过时效状态下，循环蠕变与静态蠕变相比表现出高的表观激活能，滞弹性机制作用较大。
The pull-pull cycle creep behavior of ZL107 composite at 300 ℃ was investigated by means of T5 aging and T5 +300 ℃ treatment. The experimental results show that the composite material shows the phenomenon of cyclic creep decelerating under both heat treatment conditions. Under the peak aging condition, the cyclic creep shows a lower apparent activation energy than the static creep, and the non-thermal vacancy mechanism has a greater effect Under the aging condition, the cyclic creep shows higher apparent activation energy than the static creep, and the anelastic mechanism plays a greater role.
