摘要
通过测试硬度的方法，对莫来石短纤维增强ＺＬ１０９复合材料的时效析出行为进行了研究。结果表明，由于莫来石短纤维的加入，使复合材料峰值时效硬度明显高于基体。复合材料与基体从固溶态到峰值硬度的时效动力学曲线满足指数关系。增强体的加入既能加速时效前期沉淀析出又可加快时效后期复合材料的软化，但不改变基体沉淀相的析出顺序，而只影响其析出速度。
The aging process of mullite short fibre reinforced ZL109 composites was studied via hardness test. It showed that the composite has a higher peak aging hardness value than that of matrix alloy. The aging kinetic curve of ZL109 and the composite agreed with the power function. Addition of mullite short fibre can accelerate precipitation in early aging stage and speed up composite's soften rate in later aging stage, but not alter the precipitation sequence in matrix.
