【摘要】 介绍了用磁声发射(MAE)法测定铁磁材料残余应力的分布,为此,设计了一种新型的磁化器,它可产生强而集中的磁场,可以穿透2mm 深。此法测定结果与传统的 X 射线衍射法,有较好的一致性. ,更多还原

【Abstract】 Residual stress distribution in ferromagnetic material is measured by MAE method.And a new kind of magnetizer is (?)esigned for the measurement which provide strong and concentratedmagnetic field with penetrating depth of 2mm.The result has a good consistance with that of the tra-ditional X-ray diffraction method.更多还原
