| 摘 要： | 通过化学成分分析、硬度测试、金相检验及断口分析等对汽车转向垂臂断裂原因进行了分析，结果表明，转向垂臂退火态组织硬度未达到设计使用要求及臂身表面脱碳严重，导致材料的疲劳强度降低，，造成了转向垂臂的早期断裂。

| Abstract: | The fractured steering arm was investigated by means of chemical compositions analysis, hardness test, microstructure examination and macro-fracture analysis, The results show that cause for fracture resulted from hardness of steering arm annealing could not meet the design requirements and surface of arm body decarburization seriously, so fatigue strength of the arm decreased, resulted in early fracture of steering arm. |

| Keywords: | fatigue fracture hardness decarburization microstructure |
