Science, Neodymium Magnet.
aluminum (Al) and copper (Cu) elements are added to improve microstructure homogeneity so as to increase Hcj and (BH)max. Seen from the X-ray diffraction (XRD) spectrum of sintered NdFeB magnet, it can be determined that the Nd2Fe14B tetragonal phase is the main phase in the magnet. In view of the
