摘　　要：在常规晶化退火工艺条件下纳米双相永磁合金快淬非晶薄带的晶化过程中,α-Fe相通常在低温优先析出,这导致了α-Fe晶粒过于粗大并严重损害了材料磁性能。针对这一问题,近期有一些学者对极端晶化条件下非晶快淬薄带的晶化行为和机制进行了仔细的研究。本文对这些研究进行了综述和分析。During the crystallizing process of amorphous melt-spun ribbons of nanocomposite permanent magnetic alloys under normal conditions,α-Fe phase always precipitates preferentially,which will induce coarse grains of α-Fe,and it has been proven to be detrimental to the magnetic properties.To solve this problem,crystallizing behavior and mechanisms of this kind of amorphous melt-spun ribbons under extreme conditions were studied by some researchers recently.In the present paper,these works were reviewed.
