研究了硼含量在0 ~ 0.0082wt%范围内对无取向电工钢夹杂物类型、显微组织、织构和磁性能的影响。在最终退火后，添加过量的硼（w（Bt）> 0.0041wt%）导致Fe 2B颗粒的形成。随着硼含量的增加，晶粒尺寸增加，并达到最大值在钢中的0.004 1重量%的硼。含硼量为0.0041wt%的钢具有最强的{100}纤维织构、戈斯织构和最弱的{111}纤维织构。随着硼含量的增加，磁通密度先迅速增加，然后突然下降，并在含硼0.0041wt%的钢中达到最大值。相反，铁损首先急剧下降，然后突然增加，硼含量的增加，并达到最低值，含0.004 1wt%的硼。含0.004 - 1重量%硼的钢获得了最佳的磁性能，主要是通过最佳晶粒尺寸和有利的织构的发展。
The effects of boron content in the range of 0–0.0082 wt%, on the inclusion type, microstructure, texture and magnetic properties of non-oriented electrical steels have been studied. After final annealing, the addition of excess boron(w(Bt)>0.004 1 wt%) led to the formation of Fe2B particles. As boron content increased, grain size increased and reached a maximum in steel with 0.004 1 wt% boron. Furthermore, steel containing 0.004 1 wt% boron had the strongest {100} fiber texture, Goss texture and the weakest {111} fiber texture among the five tested steels. Flux density firstly rapidly increased and then suddenly decreased with increasing boron content and reached a maximum in steel with 0.004 1 wt% boron. Conversely, core loss first sharply decreased and then abruptly increased with the increase of boron content and reached a minimum in steel containing 0.004 1 wt% boron. Steel containing 0.004 1 wt% boron obtained the best magnetic properties, predominantly through the development of optimum grain size and favorable texture.
