取向硅钢的晶体衍射花样特征研究
广泛应用于电子电力行业的取向硅钢材料的磁性能与其晶体取向密切关联，对取向硅钢晶体衍射花样的研究非常重要.采用理论计算的方式研究了取向硅钢的晶体衍射花样特征，并绘制了取向硅钢的高斯织构理论极图、理论单晶透射电子衍射斑点花样和理论电子背散射衍射(Electron backscatter diffraction, EBSD)菊池花样.取向硅钢理论单晶衍射花样不仅可以为以后标定样品实测晶体衍射花样提供一种简单快捷的方法，也可以为样品检测提供一种标准.这种研究方法不仅限于取向硅钢，也被期待应用于其他材料晶体衍射花样研究. The magnetic properties of oriented silicon steels which are widely used in electronic and power industries are closely related to their crystal orientations, so it is very important to study the crystal diffraction patterns of oriented silicon steels. The characteristics of crystal diffraction patterns of oriented silicon steels are studied by means of theoretical calculation. The theoretical pole figures, theoretical single crystal transmitted electron diffraction patterns and theoretical elec...
热轧组织对无取向硅钢织构的影响
采用X射线衍射仪分析无取向硅钢冷轧织构和再结晶退火织构的演化,研究了热轧组织对无取向硅钢织构以及磁性能的影响。结果表明,具有均匀、粗大晶粒组织的热轧板,冷轧形成更多的剪切带,导致成品板形成高的高斯织构组分,并提高了{100}织构强度,降低了γ纤维织构,最终导致成品磁感应强度升高,铁损下降。 The texture evolution of non-oriented silicon steel during cold-rolling and recrystallization annealing was investigated by X-ray diffractometer.The effects of hot band microstructure on the texture and magnetic properties of non-oriented silicon steel were analyzed.The results show that more shear bands appear during cold rolling due to homogeneous coarse grain in hot band.So strong{110}<001> texture after recrystallization annealing forms.At the same time,the {100} texture components inc...
