    摘要:

    快淬雙相納米復(fù)合稀土永磁材料非晶晶化過程決定了材料的微觀組織和磁性能。從形核規(guī)律出發(fā),提出了持續(xù)形核長(zhǎng)大和“爆炸式形核長(zhǎng)大”的非晶晶化模型。討論了快淬速度、添加合金元素、退火工藝以及外加磁場(chǎng)等對(duì)非晶晶化過程的影響,重點(diǎn)分析了合金元素在非晶晶化過程中的重新分布。在此基礎(chǔ)上,提出了利用中間相的分解細(xì)化晶粒等獲得理想材料的不同方法。

    Abstract:

    The crystallization of amorphous alloys predestinates the microstructure and magnetic properties of the melt spun nanocomposite rare earth permanent magnets. Obeying the nucleation regularity, the model of the crystallization of amorphous alloys,namely, continually and explosively nucleation and growth. is put forward. The main factors affecting it were analyzed, such as melt-spun speed, the addition of alloys and the annealing sequence with or without the applied magnetic field, Especially, the re-distribution of the alloys during crystallization. On the bases, the ideas to gain ideal grain structure were discussed, for example, refining the grains by decomposition of metastable phase.
