| Abstract: | Effect of magnetic field treatment on crystallization and magnetic properties of melt-spun Nd5.5Fe66B18.5Cr5Co5.Nd4.5Fe77B18.5 and Nd10.5Fe70B7.0Zr2.5Co10 powders were inves- tigated. Results show that an externally applied magnetic field during heat treatment of a melt-spun nanocomposite magnet can promote crystallization from amorphous State and increase the maximumeneny product. The stronger the applied magnetic field, the lower the crystallization temperature. The way to produce anisotropic NdFeB nanocomposite permanent magnet was also proposed. |
