【 摘 要 】

The cause of crankshaft fracture crack of a certain vehicle has been analyzed through macroscopic analysis, microstructure analysis, mechanical properties test and dimension inspection. The analysis results show that: the fatigue strength of the crankshaft is reduced due to spheroidization recession, low strength and shallow nitriding layer of the fillets.
