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...

利用场发射电镜及能谱仪研究了取向电工钢薄、厚板坯铸锭中不同区域的析出相差异,确定了MnS、AlN及Fe3C的析出顺序和形貌特征。结果表明AlN以先析出的MnS为形核核心,形成粗大微米级的复合析出相。针状Fe3C既可以在复合析出相表面形成也可以在基体中单独出现,主要受冷却速度的影响。在1250℃保温1～2 h,AlN、Fe3C均可完全回溶,但部分MnS仍不回溶。MnS尺寸随着保温时间延长而增大。导致热轧板中沿轧向分布的粗大MnS,减弱了粒子钉扎力。 Precipitates in thin and thick slabs of electrical silicon steel were investigated by means of field emission SEM and EDS analysis.The precipitation sequence and the morphology of MnS,AlN and Fe3C particles were identified.AlN particles are observed to be nucleated on surface of MnS forming micron-meter-sized complex particles.Acicular Fe3C can precipitate on surface of the complex MnS/AlN particles or directly from matrix depending on cooling rate of the slabs.After holding at 1250 ℃ for 1-2 h,...
