| Abstract: | The present situation of investigation and production on sintered NdFeB magnets, the theories on the NdFeB permanent alloy and the advanced production processes of sintered NdFeB magnets have been introduced in this paper. The effects of process parameters of strip casting, jet milling and rubber isostatic pressing techniques on the microstructure and magnetic properties of sintered NdFeB magnets have been emphatically overviewed. By adopting suitable component ration and applying advanced producing processes, we have succeeded in massly producing high magnetic energy product magnet with Hcj=1148kA/m(14.43kOe), (BH)max=408kJ/m3 (51.3MGOe) and high coercivity magnet with Hcj=2035kA/m(25.57kOe), (BH)max= 320kJ/m3(39.9MGOe). |
