采用单辊快淬法制备了Fe93–x Zr7Bx(x=10,12,14)合金,并对三种合金进行了不同温度退火处理,利用X射线衍射仪(XRD)、差热分析仪(DTA)和振动样品磁强计(VSM)研究了该系列合金的微观结构、热性能和磁性能。研究结果表明:B含量的增加提高了合金的第一晶化峰峰值温度。在Fe83Zr7B10合金晶化初期仅观察到α-Fe相,而在Fe93–x Zr7Bx(x=12,14)合金晶化初期可观察到α-Fe相和Fe23B6相。三种合金淬态时的Ms随B含量的增加而增大。在高于823 K的温度下退火后,三种合金的Ms随B含量的增加而减小。高于773 K退火后,三种合金的Hc随B含量的增加而增大。
The Fe93-xZr7Bx (x = 10,12,14) alloys were prepared by single roll rapid quenching. The three alloys were annealed at different temperatures. The properties of the alloys were characterized by X-ray diffraction (XRD), differential thermal analyzer ) And vibrating sample magnetometer (VSM) were used to study the microstructure, thermal and magnetic properties of the alloys. The results show that the increase of B content increases the first peak temperature of the alloy. Only α-Fe phase was observed at the early stage of the crystallization of Fe83Zr7B10 alloy, and α-Fe phase and Fe23B6 phase were observed at the early stage of crystallization of Fe93-x Zr7Bx (x = 12,14) alloy. Ms of the three alloys increases with the increase of B content when quenched. After annealing at temperatures above 823 K, Ms of the three alloys decreases with increasing B content. After annealing above 773 K, the Hc of the three alloys increased with increasing B content.
