Abstract:
Strip-casting technique is used to prepare anisotropic Nd(Fe,Mo)12Nx compounds. It is found that, by this technique, the single-phase Nd(Fe,Mo)12 compounds can be directly obtained without postannealing at a rolling velocity of 3m∕s and with an Fe-to-Mo ratio of 7. Under the same nitrogenation conditions, it is easier to introduce the nitrogen atoms into the strip-cast Nd(Fe,Mo)12 powders than into the conventionally cast powders. The microstructure studies of the ingots show that not only the size of strip cast Nd(Fe,Mo)12 grains is small, but also the size distribution of the grains is narrow as compared with those of conventionally cast ingots. Thus, the strip-casting technique is used to synthesize the anisotropic powders of Nd(Fe,Mo)12Nx with a Br of 1.10T, an Hci of 448kA∕m, and a (BH)max of 160kJ∕m3.
