铁磁材料在交变磁场的作用下,产生的巴克豪森效应,可作为无损检测材料残余应力的一种新方法。此方法检测结果与传统的X射线衍射法比较,有较好的一致性。
The Barkhausen effect produced by the ferromagnetic material under the action of an alternating magnetic field can be used as a new method for nondestructive testing of the residual stress of a material. The detection results of this method are in good agreement with the traditional X-ray diffraction method.
