摘要
本文概述了第三代稀土永磁材料的发展概况以及与 Nd-Fe-B(系)质量有关的几个问题:结晶度、颗粒度、取向度以及烧结、时效工艺细节与质量的关系;主晶相、副晶相在磁体内各自应占有的体积百分数。
This paper discribes the develepment of the third generational rare-earth magnetic material and some problems about the quality of Nd-Fe-B:Crystallinity,Graininess,Directivity and the relation between the firing,time-efficiency in details and the quality;the main crystae phase and assistant crystal phase can be in the best rate.
