	本文从微磁学角度分析外应力作用下铁磁材料内部微磁特性变化，提出并实验验证了铁磁性材料在外加应力作用下的力磁耦合致磁机制，得出外应力致磁依赖于一定的外磁化场，外磁化场与应力的相互作用导致缺陷处微磁场的泄漏，检测这个泄漏场可实现外应力作用下铁磁构件的缺陷检测，为损伤缺陷微磁检测提供了理论支撑。<br />
From the point of micromagnetics, the characteristic change of internal micromagnetic filed in ferromagnetic material was analysed under the external stress. It was proposed and verified by experiment that the mechanism of Magneto-Mechanical coupled induced magnetic field for the ferromagnetic material under external stress is depended on the external magnetizing field. With the interaction of external magnetizing field and stress, the micromagentic field in the defects is leaked, which is the basement of micomagetic testing.
