摘要: 利用EBSD和XRD等表征手段,研究了850 ℃不同退火时间对1.0%Si无取向硅钢冷轧板组织及织构的影响。结果表明,850 ℃退火90 s时冷轧板已经基本完成再结晶,织构类型由强α、旋转立方织构{001}<110>向γ织构{111}<112>和α*织构转变;退火90 s至180 s时晶粒逐渐长大,平均晶粒尺寸由14.2 μm增加至21.3 μm,α*织构以及旋转立方织构{001}<120>逐渐增强,磁感B5000从1.55 T增加至1.63 T,铁损P1.5/50从4.213 W/kg降低至3.832 W/kg。

Abstract: Effect of different annealing time at 850 ℃ on the microstructure and texture of 1.0%Si non-oriented silicon steel cold-rolled sheets was investigated by means of characterization techniques such as EBSD and XRD. The results indicate that the cold-rolled sheets undergo recrystallization when annealed at 850 ℃ for 90 s. The texture type transforms from strong α and rotated cube texture {001}<110> to γ texture {111}<112> and α* texture. When annealed from 90 s to 180 s, the grain size gradually increases, with the average grain size growing from 14.2 μm to 21.3 μm. The α* texture and rotated cube texture {001}<120> strengthen gradually, the magnetic induction B5000 increases from 1.55 T to 1.63 T, and the iron loss P1.5/50 decreases from 4.213 W/kg to 3.832 W/kg.
