| 中文摘要: |
| 分别采用磁性法、金相方法和X射线衍射法测量了GCr15轴承钢中的残余奥氏体含量，探讨了残余奥氏体含量对GCr15轴承钢使用寿命的影响。结果表明，磁性法测量GCr15轴承钢中残余奥氏体量快捷、准确，易于实现产品生产中的在线快速检测，轴承钢中残余奥氏体对轴承运行过程中疲劳寿命的影响，必须结合应力形态、分布、运行状态及诱发马氏体转变性能等方向进行综合研究来评价。 |
| 英文摘要: |
| The retained austenite content in bearing steel GCr15 was determined by magnetism method, metallographic analysis and X-ray diffraction measurement, its effects on the service life of bearing steel GCr15 were also discussed. The results show that magnetism method facilitates the determination of the retained austenite content in bearing steel GCr15 by speediness and accuracy, the effects of the retained austenite content in bearing steel on the fatigue life of the working bearing should be evaluated by comprehensive investigations combining stress form, distribution, running state and the induced martensite transformation characteristics. |
