采用优化的氢化还原-脱附复合工艺制备了最大磁能积为216 kJ m-3的各向异性Pr 13 Fe 80 B7磁粉。产物为棒状结构，自组织六方PrH 2纳米棒嵌入Fe基体中. B元素出现在高度有序的棒状区域之间。粉末中高度有序的棒状结构和B的特殊分布是粉末中高度织构取向的原因。
Anisotropic Pr13Fe80B7magnetic powders with a maximum energy product of 216 kJ m–3were prepared through an optimized hydrogenation disproportionation desorption recombination process. The disproportionated products display a rod-like microstructure with self-organized hexagonal PrH2nanorods embedded in Fe matrix. B element appears between the highly ordered rod-like regions. Both the highly ordered rod-like structure and the specific distribution of B in the disproportionated microstructure are responsible for the high degree of texture orientation in the powders.
