Abstract：

Melt　spinning　is　an　effective　method　for　preparing　nanocrystalline　permanent　magnet　materials.　During　the　rapid-quenching　process,　uneven　undercooling　can　easily　lead　to　uneven　distribution　between　the　ribbons.　Due　to　the　difference　in　cooling　speed　between　the　roller　surface　and　the　free　surface,　the　microstructure　in　one　ribbon　is　also　uneven.　In　this　work,　to　solve　the　problem　of　poor　uniformity　of　the　melt-spun　(Nd,Pr)-Fe-B　ribbons　obtained　by　direct　rapid-quenching,　appropriate　short-time　annealing　had　been　implemented.　The　microstructure　and　magnetic　properties　of　the　melt-spun　(Nd,Pr)-Fe-B　ribbons　before　and　after　annealing　showed　a　significant　improvement　in　the　uniformity.　The　improvement　of　uniformity　could　be　beneficial　for　the　application　of　melt-spun　powders　in　bonded　magnets　and　hot-deformed　magnets,　enhancing　the　magnetic　properties　of　related　products.　IEEE
