| Abstract: | The present paper covers the HDD process. The isotropic magnetic powders were prepared by HDD process. We have analysed the magnetic powders by the method of X-ray diffraction. The bonded magnet prepared from the magnetic powders possesses the following properties:iH_c=896kA/m, B_r=0.51T, (BH)_(max)=44kJ/m~3. |
