Abstract The effect of adding of 0.13 wt% Cr on the primary recrystallization and magnetic properties of high permeability grain oriented silicon steel was studied. The results show that trace Cr refined both primary and secondary grains. The reduction of final grain size resulted in decrease of 5.1%, 4.0% and 3.6% in the average of iron loss during magnetization at 50 Hz, 100 Hz and 200 Hz, respectively. Besides the conventional precipitates, there were two kinds of Cr-containing nitrides, i.e., the amorphous (Si, Cr) N formed in the matrix, and the crystalline fcc-CrN formed at grain boundary. These precipitates acted as inhibitors to refine and homogenize primary grains in the thickness direction. The beneficial {1 1 1} 〈1 1 2〉 texture component increased, while the components that cannot form high-energy grain boundaries with Goss grains, such as {0 0 1} 〈1 1 0〉 and {1 1 2} 〈1 1 0〉 at different thickness layers decreased after primary recrystallization.

添加微量Cr对高磁导率取向硅钢一次再结晶特性及磁性能的改善

摘要 研究了添加0.13 wt% Cr对高磁导率取向硅钢一次再结晶和磁性能的影响。结果表明微量铬精炼了初生和次生晶粒。最终晶粒尺寸的减小导致在 50 Hz、100 Hz 和 200 Hz 磁化过程中平均铁损分别降低 5.1%、4.0% 和 3.6%。除常规析出物外，还有两种含Cr氮化物，即基体中形成的非晶(Si, Cr) N和晶界处形成的晶态fcc-CrN。这些沉淀物作为抑制剂在厚度方向上细化和均匀化初级晶粒。有益的{1 1 1} 〈1 1 2〉织构成分增加，而不能与高斯晶粒形成高能晶界的成分，
