| 摘 要： | 45钢制手柄轴，由于其直径是对淬火开裂敏感的尺寸，加之有网状铁素体和魏氏组织等原材料缺陷．淬火时常常开裂。采取正火处理和适当降低奥氏体化温度及预冷淬火等措施，取得了防止手柄轴淬裂的令人满意的效果。

| Abstract: | 45 steel handle shafts cracked frequently during quenching because of the diameter susceptible to quench cracking and such defects as ferrite network and Widmanstatten structure present in the raw material.The quench cracking of the handle shaft has been satisfactorily avoided by normalizing,proper decrease in austenitizing temperature or delayed quenching. |
