| Abstract |
In order to evaluate the anisotropic magnetic properties of steel sheets, analytical expressions based on the orientation distribution function of samples were proposed and compared with experimental data in a Fe-3%Si single crystal. The magnetic anisotropy was measured by means of vibrating sample magnetometer(VSM) and the orientation was determined by X-ray texture goniometer. Anisotropy of the magnetic properties is found to be dependent on the magnetization energy which varies as a function of the crystallographical direction. Applying the measured magnetic properties to the analytical expressions, the anisotropy constants of K₄= 36500 J/㎥ and K_6 = 1000 J/㎥ were calculated. The highest magnetic permeability and flux density were obtained in the easy magnetization direction of [100]. The orientation independent magnetization energy of the Fe-3%Si single crystal was 16330 J/㎥. |
