Abstract:
      Thin strips of Nd(FeTi)12/ɑ-Fe and Nd(FeTiNb)12/ɑ-Fe alloys were prepared by vacuum arc melting and melt quenching processes to investigate the effects of the addition of Nb elements and different nitriding temperatures on the microstructure and magnetic properties of the alloys. The results show that the addition of Nb elements significantly refines the grain size and increases the amorphous formation rate of the alloy. The magnetic properties of Nd(FeTiNb)12N/ɑ-Fe strips were significantly increased after crystallisation annealing and nitriding, and the best magnetic properties were achieved at a nitriding temperature of 500 °C, when the remanent magnetisation (Br) and coercivity (Hcj) were 21.9 emu/g and 700 Oe, respectively.
