研究了不同的磁场退火方式对非晶合金铁芯磁性能的影响。结果表明，纵向磁场退火后非晶合金铁芯的剩磁、最大磁导率和损耗增加；横向磁场处理后非晶合金铁芯的剩磁、最大磁导率、损耗和矫顽力减小；先加横向磁场后加纵向磁场退火，非晶合金铁芯可同时获得高的剩磁和低的损耗。
Amorphous metallic cores were annealed in different magnetic field. The magnetic properties of the cores after annealing were examined. The results show that remanence, magnetic permeability and core losses increase after annealing in longitudinal magnetic field, while decrease in transverse magnetic field. High remanence and low core loss can be obtained after annealing in longitudinal magnetic field following in transverse magnetic field.
