| 摘 要： | 对3种不同预应变量的碳素钢实施时效处理,并进行弯曲疲劳实验,实验结果表明：材料的疲劳极限同时受预应变量和时效处理温度的影响,使其疲劳极限为最大值时所对应的最优时效处理温度随预应变量的增大而降低。

| Abstract: | In this paper, the carbon steel samples with three kinds of pre-strains were treated by aging, and the bending fatigue test were carried out on these samples. The results show that the fatigue limit of the materials is affected by the pre-strain and the temperature of the strain aging. When the fatigue limit is the maximum, the optimal temperature of the strain aging may decrease with the increase of the pre-strain. |
