运用电子背散射衍射(EBSD)技术,研究了50W600无取向硅钢在热轧→冷轧→退火工序间织构的演变。结果表明:由于热轧板沿板厚方向的应力场和温度场存在差异,导致热轧板不同层织构类型和强度存在差异;热轧板表层主要存在铜型、黄铜和高斯织构,1/4层织构主要为α纤维织构和较弱的高斯织构,中心层织构较单一,主要为α纤维织构;和热轧板相比,冷轧板各层织构差异较小,为典型的轧制织构(α纤维织构和γ纤维织构);退火板各层都表现为γ纤维织构增强、α纤维织构减弱,旋转立方织构基本消失。 The texture evolution of 50W600non-oriented silicon steel in hot rolling,cold rolling and annealing process was investigated by electron back-scatter diffraction(EBSD)technology.Results show that the hot rolled plate texture types and intensities along thickness direction were different because of the different stress fields and temperature fields.The major texture types in the surface of hot rolled plate were copper,brass and Gauss texture.The texture was composed ofαfibre texture and weaker Ga... 

对商用50W330型无取向硅钢成品在930℃下保温2 h固溶并以不同方式冷却处理,利用磁性检测仪检测分析了处理前后的磁感和铁损变化,应用光学显微镜、扫描电子显微镜、X射线衍射仪观测分析了显微组织结构的演变。考察了平均晶粒尺寸、织构组分比及第二相粒子状态对磁性能的影响规律,结果表明:固溶处理前后平均晶粒尺寸的变化对硅钢磁性能的影响非常显著;当平均晶粒尺寸相差不大时,织构组分比[Goss+{100}]/{111}越大,磁感会越高;固溶处理会将细小弥散的第二相粒子重新回溶到基体中,减小了其对磁畴壁的钉扎作用,铁损随之下降。 The commercial 50W330 non-oriented silicon steel samples were heat treated at 930℃ for 2 h and cooled in different ways,then the iron loss and the magnetic induction of the samples before and after solution treatment were measured with a magnetic detector.The evolution of microstructural texture was analyzed by optical microscopy,scanning electron microscopy and X-ray diffractometry.The effects of average grain size,texture composition ratio and the second phase particles on the magnetic propert...
