对于旋转弯曲疲劳试验中间停歇对疲劳极限的影响,我们测试了60Si2Mn弹簧钢在室温下连续试验的疲劳极限和中间停歇试验的疲劳极限,并进行了对比,研究了中间停歇对60Si2Mn钢疲劳极限的影响。一、试验条件 1.试验用钢采用首都钢铁公司生产的纯氧顶吹60Si2Mn弹簧钢。其化学成分和机械性能列于表1和表2。
The fatigue limit of 60Si2Mn spring steel at continuous room temperature was tested and the fatigue limit of the intermediate stop test was tested for the effect of middle stoppage on the fatigue limit. The effects of middle stop on the fatigue limit of 60Si2Mn steel influences. First, the test conditions 1 test steel produced by the Capital Iron and Steel pure oxygen top blowing 60Si2Mn spring steel. Its chemical composition and mechanical properties are listed in Table 1 and Table 2.
