Reason Analysis on Cracks in Centrifugal Wheel Blade

CHEN Rui 1,2,LIU Xin-ling 2,CAI Xian-xin 3,CHEN Xing 2 (1.Key Laboratory of Nondestructive Testing of Ministry of Education,Nanchang Hangkong University,Nanchang 330063,China;2.Beijing Institute of Aeronautical Materials,Beijing 100095,China;3.China Aviation Power Plant Institute,Zhuzhou 412002,China)  
The cracks were found in border of centrifugal wheel blade of an engine.The reason of cracks was analyzed by means of physical testing and chemical analysis,quantitative analysis and calculations for crack propagation life and expand total percentage of the propagation life.The results showed that the cracks in blade was high cycle and low cycle composite fatigue cracks,and fatigue cracking occured in blade by large stress of abnormal vibration.
