| 摘 要： | 通过硬度检测、金相检验、宏观及微观断口分析， 结合力学分析证实了汽轮机轴失效是由于轴肩变径处加工刀痕导致应力集中，造成多条疲劳 裂纹萌生、扩展及最终的断裂，提出了防止汽轮机轴疲劳断裂的措施.

| Abstract: | The failure of a turbine axes was investigated by sclerometer,optical microscopy,SEM,and mechanics analyses.It has been found that the surface-machining nick,which resulted in stress concentration,which induced initiation and grow of fatigue cracks,and finally rupture of the axes.According to the experiment results,measures to prevent the fatigue failure have been suggested. |
