摘　　要：介绍了纳米晶软磁合金磁场退火后合金晶化行为和磁畴结构的变化。相对于无磁退火,磁场退火可以起到细化晶粒、提高纳米晶粒形核率的作用,从而使合金中晶体相所占的比重得到增加,软磁性能得到改善;磁场退火后,合金的磁畴结构中钉扎位消失,磁畴界面清晰,多沿外场方向分布。The change of crystallization behavior and magnetic domain structure of magnetic field annealing for nanocrystalline soft magnetic alloys is introduced.Compared with non-magnetic annealing,magnetic field annealing can refine grains and increase the nucleation rate of nanocrystalline grains,thus increasing the proportion of crystal phase in the alloy and improving the soft magnetic energy.After magnetic field annealing,the pinning position in the magnetic domain structure of the alloy disappears,the magnetic domain interface is clear,and most of them are distributed along the external field.
