| 中文摘要: |
| 采用化学、金相及扫描电镜（SEM）等方法对两根表面具有裂纹的驱动轴的裂纹产生的原因进行分析。结果表明：A驱动轴的裂纹属于淬火裂纹，是热处理过程中产生的；B驱动轴的裂纹是钢材本身的内部杂质所致。 |
| 英文摘要: |
| The causes of crack for the two drive shafts were researched through chemical, metallographic and scanning electron microscopy (SEM) analyses. The results show that the crack of A drive shaft belongs to the quenching crack which is produced in the heat treatment process; the crack of B drive shaft is caused by internal inclusions in steel. |
