【摘要】：采用EBSD分析技术对冷轧无取向电工硅钢和冷轧取向电工硅钢的晶粒取向特征进行了研究。结果表明,无取向电工硅钢轧制表面的OIM图呈多种颜色分布,晶界取向差在18.9°~37.4°之间,晶粒度6.0~10.0级,在反极图上,(001)、(101)和(111)晶面有漫散的织构存在。取向电工硅钢轧制表面的OIM图的色彩单调,晶粒粗大,晶界取向差在7.9°~16.0°之间,在反极图上,仅(101)晶面有锋锐的织构,(001)和(111)晶面没有织构存在。根据OIM图和反极图的分析,可以鉴别电工硅钢的晶粒取向。
[Abstract]:The grain orientation characteristics of cold rolled non oriented electric silicon steel and cold rolled oriented electric silicon steel were studied by EBSD technique. The OIM diagram of the rolled surface of non-oriented electrical silicon steel shows a variety of color distributions. The grain boundary orientation difference is between 18.9 掳and 37.4 掳, and the grain size is 6.0 ~ 10.0 grade. The OIM diagram of oriented electric silicon steel rolling surface is monotonous, the grain size is coarse, and the grain boundary orientation difference is between 7.9 掳and 16.0 掳. On the reverse pole diagram, there is no texture on the face of only 101) crystal plane. According to the analysis of OIM diagram and inverse pole diagram, the grain orientation of electrical silicon steel can be identified.

【正文快照】： 冷轧无取向电工硅钢和冷轧取向电工硅钢是重要的软磁材料,海关依据电工硅钢的晶粒取向性质,实施不同的进出口监管和征税条件。取向电工硅钢特别是高磁感Hi-B钢,因其制备技术的复杂性、精准性和高附加值,在监管方面又有专门的规定,而以废物、二次油片报关的硅钢也需要根据晶粒
