摘要
使用光学、电子等微观手段及宏观力学分析方法证明,由不均匀的温度分布所引起的热应力、燃气中的腐蚀性介质及铸态组织中的枝晶是引起涡轮叶片开裂的主要原因。本文还对提高其使用寿命的方式进行了探讨。
t was proved by the optical and electronical microanalysis methods and mechanical analysis that the thermal stress,corrosive medium in burned gas and dendritic structure of the vane were main reasons for the cracking of the turbine nozzle vane. The way to improve the service life of the vane was suggested.
