摘要
通过金相法和磁声发射法（ＭＡＥ）研究了高牌号无取向硅钢脱碳退火时所产生的内氧化层。这种氧化层使钢板产生应力场，阻碍磁畴壁的位移，因而使铁损增加。
The subsurface oxide layers generated during decarburizing annealing of high grade non-oriented silicon steel sheet were studied by metallographical method and magnetoacoustic emission method(MAE).The subsurface oxide layers generated stresses in the sheet and impeded domain wall motion,so that the iron loss was increased.
