摘要
Φ8～Φ12是45钢的水淬淬裂危险尺寸。通过对具有淬裂危险尺寸45钢小工件的工艺改进，探讨了亚温淬火的作用机理。
45# steel with Φ8~Φ 12 diameter is the possible quench crack size in water quench- Based on quench technique improvement on 45# steel small elements being of possible quench crack s1ze,the mechanlsm of subnormal temperature quench is discussed.
