本文根据三维取向分析的广义矢量法,分别确定W20冷轧无取向硅钢片的表面层、1/4层及中心层的晶粒取向分布函数(ODF);扩展运用晶粒取向分布无样品对称多晶材料之磁各向异性理论,定量算出板片上不同方向的磁转矩。理论预算值与实测磁转矩曲线符合较好。

The crystallite orientation distribution functions(ODFs)were determined for the surface, 1/4 depth and 1/2 depth layers of a cold-rolled W20 non-oriented silicon steel sheet.By extending the theory of magnetic anisotropy to textured materials with no sample symmetry, the variation of magnetic torque versus directions in the plane of the sheet was further calcu- lated quantitatively,which fits well with the measured torque curve.
