为了研究取向硅钢织构与电学性能之间的关系，进行了逐晶取向测量。刻蚀被用来产生由(100)立方平面组成的多面体表面，从而使每个颗粒在三个垂直方向上明亮地反射。光学测角仪被用来确定每个颗粒的晶体取向。取向定义为以下三个角度：(1)α-[001]方向与轧制方向在板材平面上的发散，(2)β-[001]方向相对于轧制方向的垂直倾斜，(3)γ-(110)平面围绕磁化方向的旋转。统计方法被用来根据这些角度的扩散或分布来计算织构的程度，并将分布与电学性质相关联。在10H时，α与渗透率之间存在很强的相关性，约75%的10H时渗透率的变化可以通过α的变化来解释。只有大约55%的铁损变化可以通过α的变化来解释。β与通透性的相关性不显著。γ角应该不会显著影响电学性质，也没有发现相关性。
Grain‐by‐grain measurements of crystallographic orientations have been made to study the relationship between texture and electrical properties of oriented silicon steel. An etch was used to produce a faceted surface of (100), cube, planes thus making each grain brightly reflective in three perpendicular directions. An optical goniometer was used to determine the crystallographic orientation of each grain. Orientation is defined in terms of three angles as follows: (1) α‐the divergence in the plane of the sheet of the [001] direction from the rolling direction, (2) β‐vertical tilt of the [001] direction from the rolling direction, (3) γ‐the rotation of the (110) plane about the direction of magnetization. Statistical methods were used to calculate the degree of texture in terms of the spread or distribution of these angles and to correlate the distribution with electrical properties. A strong correlation was found between α and permeability at 10 H. About 75% of the variation in permeability at 10 H could be accounted for through variations in α. Only about 55% of the variation in core loss could be accounted for through variations in α. Correlation of β with permeability was not significant. The angle γ should not appreciably affect electrical properties and no correlation was found.
