本文用透射电镜研究了Fe_（78）B_（13）Si_（9）合金在淬火态和晶化态的显微组织与磁畴结构的相互关系。对部分晶化过程中形成的晶体与畴壁的相互作用也作了初步研究。在淬火状态下的畴结构由大的畴，其中磁化方向主要由静磁效应决定。结晶的开始伴随着相当大的细化的域的大小。当样品接近完全结晶时，磁畴结构变得越来越复杂，现场实验表明，结晶产物是磁畴壁的钉扎点。
A transmission electron microscope study of the interrelation between microstructure and magnetic domain configuration in the alloy Fe78B13Si9both in as-quenched and crystallized states has been made. A preliminary investigation of the interaction of the domain walls with crystals formed during partial crystallization has also been made. The domain structure in the as-quenched state consists of large domains in which magnetization directions are determined mainly by magnetostatic effects. The onset of crystallization is accompanied by a considerable refinement of the domain size. As the specimen approaches complete crystallization, the domain structure becomes increasingly complex.In situapplied field experiments demonstrate that the crystallization products act as pinning sites for domain walls.
