| 摘 要： | 金属磁记忆检测可以对应力集中早期预报，不同应力状态下铁磁性构件的磁记忆信号分布在发生变化。通过对一批预埋缺陷的钢棒进行静载荷拉伸试验，检测钢棒拉伸装夹前后、拉伸前后、拉伸卸下前后和拉伸过程中的磁记忆信号分布变化，对产生的磁记忆现象与应力场的关系进行了较深入定性的初步探讨。

| Abstract: | The metal magnetic memory testing method can diagnose stress concentrate zone of the ferromagnetic which the damage is going to appear in advance, thus realize to predict destruction. The magnetic memory signal distributing of the ferromagnetic have been changed by different stress state. A passel of steel bar have been made to primary discuss the embedded relation of magnetic signal distributing and stress field under static tension experiment before and after loading, the tension course and offloading and during the tension course. |
