摘要
为研究常化温度对热轧无取向硅钢组织与织构的影响,采用光学显微镜、背电子散射衍射技术研究了不同常化温度对其影响。结果表明,实验硅钢板在700～850℃温度下常化时,随常化温度的升高,晶粒尺寸增大,有利组分α织构增强,不利组分γ织构降低。对比研究了800℃和850℃常化热轧板CSL晶界分布图与取向差分布图,在本文研究条件下,Goss织构易在Σ=3,9的CSL晶界及晶粒取向差为30°～55°处形成。
The hot strips normalized at different temperatures were investigated by optical microscope and EBSD to study the effect of normalizing temperature on microstructure and texture of hot-rolled non-oriented silicon steel sheets.The results show that the grain size increases,the intensity of α-fibre texture increases,and the γ-fibre texture decreases when the hot strips are normalized at the 700-850 ℃.And CSL boundaries of Σ=3 and 15,and misorientation angles between 30° and 55° are more likely related to the growth of Goss grains,by comparative studying the CSL boundary and misorientation distribution for the hot strips normalized at 800-850 ℃.
