空气压缩机叶片断裂失效分析
Failure Analysis of Air Compressor Blade
摘要
Abstract
The macro and micro feature of failure blade,chemical composition of fracture surface,metallography and hardness were analyzed by SEM,EDS and optical microscope.The results revealed that lower hardness of failure blade resulted in decreased resistance to high cycle fatigue properties.The fatigue crack which caused final rupture initiated from the inclusion near surface.关键词
