| 中文摘要: |
| 采用断口分析、显微组织检验、低倍组织检验和化学成份分析等方法，对45钢汽车稳定杆进行了失效分析。断裂失效的主要原因是由于材料的成分偏析、热处理工艺不当和表面缺陷造成的。建议改进热处理工艺，保证组织的均匀性；选用成分均匀的钢材。 |
| 英文摘要: |
| The failure analysis of the automobile stabilizing rod which is made of 45 steel was made through fracture microscopic analysis, microstructure test, macrostructure test and chemical compositions analysis. The main causes of the fracture failure were composition segregation, improper heat-treating process and surface defect. Improving the heat-treating process to ensure the uniformity of microstructure and selecting the steel with uniform ingredients were suggested. |
