| 中文摘要 | The structure and permanent magnetic properties of isotropic powders of NdFe12-xMox (1 less than or equal to x less than or equal to 2) and their nitrides were investigated by using mechanical alloying. It was found that heat treatment of as-milled powders at 850 similar to 900 degrees C resulted in the formation of the Nd(Fe,Mo)(12) phase. The metastable Nd(Fe,Mo)(7) phase and a large amount of alpha-Fe were present at 800 degrees C. After nitrogenation, the volume expansion of NdFe12-xMox phases was about 3.5% and the Curie temperature of the samples was enhanced by 157 similar to 207 degrees C. In NdFe12-xMoxNy compounds the values of T-c fall in the range of 272 similar to 75 degrees C. It has been found that the intrinsic coercivities strongly increased with increasing Mo content. The maximum coercivity, H-i(c)=7.8 kOe, was achieved at 850 degrees C for the sample with x=2. The difference between the coercivities of the mechanically alloyed Nd(Fe,Mo)(12)N-y powders with different Mo content was attributed to their different crystallization behavior.
