研究了添加Zr对纳米复合Pr2Fe14B/α-Fe永磁合金形成、组织结构及磁性能的影响。结果表明,对于三元的Pr8Fe86B6非晶带的晶体过程,在晶化最终产物Pr2Fe14B+α-Fe形成之前出现Pr2Fe23B3亚稳相。而Pr8Fe85Zr1B6非晶带的晶化过程不出现亚稳相。添加Zr元素显著地提高了纳米复合永磁合金的磁性能。
The effects of Zr addition on the formation, microstructure and magnetic properties of nano-composite Pr2Fe14B / α-Fe permanent magnet alloys were investigated. The results show that for the ternary Pr8Fe86B6 amorphous ribbons, the metastable Pr2Fe23B3 phase appears before the formation of Pr2Fe14B + α-Fe, which is the final crystallization product. The crystallization of Pr8Fe85Zr1B6 amorphous zone does not appear metastable phase. The addition of Zr element significantly improves the magnetic properties of the nano-composite permanent magnet alloys.
