| 摘 要： | 使用82 Hz轴向加载疲劳试验机和20 kHz非间歇式加载的超声疲劳试验机,对比研究了超声加载频率对轴承钢GCr 15和35CrMo超长寿命疲劳性能的影响.断口观察表明:82 Hz轴向加载和20 kHz超声加载的GCr15试样,在全应力幅范围既发生表面破坏又发生由夹杂物引起的内部破坏；而35CrMo试样在两种频率下均为...

| Abstract: | In order to investigate the frequency effect on giga-cycle fatigue properties in giga-cycle region,ultrasonic(20 kHz) and cyclic axial(82 Hz) loading tests were carried out for GCr15 and 35CrMo steel using plain specimens.Fracture observation shows that axial loading GCr15 samples and ultrasonic samples,in all the stress amplitude range have both surface damage and internal damage caused by inclusion,and both 35CrMo axial loading samples and ultrasonic samples have surface crack damage.The stress intensity ... |
