摘要：

Morphological alloy of Nd4.5Fe76.3Ga0.2Co1.0B18 prepared by rapid quenching was crystallized to obtain the nanocrystalline permanent magnetic materials in which Fe3B and Nd2Fe14B were the dominant phases. The X-ray diffraction method, the transmission electron microscopy technique and magnetic measurement were used to analyze the microstructure and magnetic properties of the nanocomposite materials. The relationship of the microstructure, the magnetic properties with the exchange coupling interaction between crystallites was studied by determining the delta M curve of the nanocomposite magnets.
