| 摘 要： | 以巴克豪森噪声(BN)原理为基础测量曲轴热处理后残余应力。结果表明调质后表面残余应力为压应力,定型工序是可以删除的,中频淬火后表面残余应力为压应力。取消定型有利于防止曲轴的变形和开裂。

| Abstract: | Based on Barkhausen Noise ( BN ), heat treatment residual stresses of crankshafts were practically measured.It has become apparent that surface residual stresses are compressive after the quenching of medium frequency & hardening and tempering,elimination of annealing treatment for relieving stress is feasible. |

| Keywords: | BN residual stresses NDT |
