中文摘要：通过对34CrMo汽轮机主轴动断裂进行材料成分、力学性能、断口形貌、夹杂物以及显微组织等方面的分析，确定失效发生的原因是由于汽轮机主轴在动平衡实验中发生过载引起。
英文摘要：The fracture process was analyzed about the quenching and tempering steel 34CrMo during the dynamic balance experiment. The material characteristics, such as: chemical composition, mechanical properties, fracture morphology, inclusion and microstructure, were analyzed. And the cause of fracture accident was confirmed, it is mainly due to overload, which happens in turbine spindle dynamic balance experiment.
