摘要
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。
Fe93-xZr7Bx（x=10, 12, 14） amorphous alloys prepared by single-roller melt-spinning were annealed at various temperatures. The microstructures, thermal properties and magnetic properties of the prepared Fega-xZr7Bx（x=10, 12, 14） alloys were investigated by X-ray diffraction （XRD）, differential thermal analysis （DTA） and vibrating sample magnetometer （VSM）. The results show that the first crystallization peak temperature of the prepared alloys increases with the increasing orB content. At beginning crystallization stage, only the ct-Fe phase is observed in the Fe83Zr7B10 alloy, while both the ct-Fe and FeE3B6 phases are observed in the Fe93-xZr7Bx （x=12, 14） alloys. Ms of three kinds of as-quenched alloys increases with the increasing of B content. After annealing at temperatures above 823 K, Ms of three kinds of annealed alloys decreases with the increasing of B content. Hc of three kinds of alloys annealed over 773 K increases with the increasing of B content.
