PREDICTION OF MAGNETOCRYSTALLINE ANISOTROPY OF POLYCRYSTALLINE MATERIALS WITH GENERALIZED VECTOR METHOD
广义矢量法预估多晶材料的磁晶各向异性

The orientation distribution function of the crystallites in a cold-rolled W20non-oriented Si steel sheet was determined for the layers along surface, 1/4 depth and centre, res-pectively, with the generalized vector method. The angular variation of magnetic torque in thesheet plane was quantitatively calculated by extending the theory of magnetic anisotropy to thepolycrystalline materials with no sample symmetry. The values predicted theoretically are wellfit to the magnetic torque plot measured.
