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。
The aging kinetic curve of ZL109 and the composite agreed with the power function.
结果表明，预变形可以提高合金的峰值硬度，合金峰值硬度的增加来自于S 相数目的增加和尺寸的减小；
The results show that the peak hardness of pre-deformation sample is increased because of quantity increase and refinement of S phase.
随着温度的升高，达到硬度峰值所需的时间越短。
With the increasing of ageing temperature, time is shortened reaching hardness peak.
