Failure analysis of spring steel stabilizer bar

PENG Wen-yi,ZHANG Jian(School of Materials Science and Engineering,Nanchang University,Nanchang Jiangxi 330031,China)  
Through morphology observation,hardness test,microstructure inspection and spectrum analysis,failure causes of 60Si2Mn spring steel were studied as well as the impact factors of failure,such as inclusions,surface decarburization,surface defects and so on.The results show that the fracture of spring steel is early fatigue fracture,with cracks initiating at the surface and sub-surface areas.
