提出了利用坐标变换的三维多晶磁场分析方法。局部坐标在每个晶粒中是固定的，全局坐标是在多晶钢中定义的。尽管假设每个晶粒具有与单个晶粒相同的磁化特性，但仍考虑晶粒形状及其α、β和γ角的取向。当该模型应用于具有56个晶粒、尺寸为80mm×80mm、厚度为0.35mm的真实晶粒取向（GO）钢时，计算结果与X射线衍射测量的晶粒取向进行了比较。 GO钢具有较高程度的(110)[001]织构，硅含量约为3%。实际GO钢中较高磁通密度部分和较低磁通密度部分的计算结果通过α角分布进行解释。计算的倾角分布和测量的α角分布似乎非常吻合。计算出的磁通密度法向分量反映了真实GO钢的β角分布。结论是所提出的 3D 多晶磁场分析是合适的。
The 3-D polycrystal magnetic field analysis method by means of coordinate transformation is proposed. The local coordinates are fixed in each crystal grain and the global coordinates are defined in the polycrystal steel. Though it is assumed that each crystal grain has the same magnetized characteristics as those of a single crystal grain, the crystal grain shape and its orientations of alpha, beta, and gamma angles are taken into account. When the proposed model is applied to the real grain oriented (GO) steel with 56 crystal grains in 80-mm × 80-mm, and with 0.35-mm thickness, the calculation results are compared with the grain orientations measured by X-ray diffraction. The GO steel has a higher degree of (110)[001] texture with about 3% silicon. The calculated results of higher magnetic flux density part and lower magnetic flux density part in the real GO steel are explained by the alpha angle distribution. The calculated inclination angle distribution and the measured alpha angle distribution seem to be in good agreement. The calculated normal component of the magnetic flux density reflects the beta angle distribution of the real GO steel. It is concluded that the proposed 3-D polycrystal magnetic field analysis is appropriate.
