Failure Analysis of Automobile Crankshaft Cracking in Heat-treatment
Failure analysis of the surface cracks of 42CrMo automobile crankshaft was performed with EMPA,EDS and metallographic examination.The results show that the apparent and non-metallic inclusions existing in the raw materials and segregation in the composition of grain-boundary were the reason why quench caused the cracking at the surface of the crankshaft.
