“…Until now, sintering and bonding have been the the main techniques for processing Nd-Fe-B magnets; the copper mold casting method that provides a simpler and more economical approach to develop bulk permanent magnets has been adopted to produce Nd-Fe-B magnets [1,2]. However, use of the casting method is limited by the poor magnetic properties of products, which rely strongly on the materials' microstructures.…”

The isothermal solidification [liquid → T1 (Nd2Fe14B) + α-Fe + amorphous phase] of supercooled Nd–Fe–B alloy was simulated by a phase-field method, and the effects of external magnetic field on microstructural evolution were investigated. It was demonstrated that an external magnetic field could refine grains, promote formation of texture and inhibit formation of the amorphous phase during the solidification process. Further, the demagnetization curves of various microstructures solidified under different conditions were calculated by micromagnetic simulations. It was found that the magnetic properties of Nd–Fe–B magnets could be improved by the effects of a magnetic field on solidification structures.
