摘　　要：从力学性能、高低倍组织等方面对首批国产化的核电汽轮机组低压末级长叶片进行了解剖试验研究,并根据设计需要,进行了高周旋转弯曲疲劳和高频疲劳性能试验,得出的试验结果不仅可为核电机组的结构设计提供数据支持,而且能更好地保证核电机组运行的可靠性和安全性。Carry out the anatomical test of the first domestically produced blades used for nuclear power steam turbine LP last stage from the aspects of mechanical properties, macrostructure and mierostructure, and according to the design needs, high cycle bending fatigue and high frequency fatigue test were also carried out. The test results can not only provide data support for the structural design of nuclear power plant, but also can better ensure the reliability and safety of nuclear power plant operation.
