采用单辊快淬法制备(Fe1-x Cox)80Zr10B10(x=0,0.1,0.2,0.3)非晶合金,并对4种合金在不同温度下进行等温热处理。利用差热分析仪(DTA),X射线衍射仪(XRD),透射电镜(TEM)和振动样品磁强计(VSM)等测试手段对样品的热性能、微观结构及磁性能进行研究。结果表明,未添加Co元素的Fe80Zr10B10合金的热稳定性明显高于添加Co元素的合金,而(Fe1-x Cox)80Zr10B10(x=0.1,0.2,0.3)合金的热稳定性相差不大。Fe80Zr10B10和Fe72Co8Zr10B10合金的晶化过程相似;Fe64Co16Zr10B10和Fe56Co24Zr10B10合金的晶化过程相似。4种合金的矫顽力(Hc)呈现先上升后下降的趋势,在873 K达到最大值。
The (Fe1-x Cox) 80Zr10B10 (x = 0,0.1,0.2,0.3) amorphous alloy was prepared by single roll rapid quenching method, and the four alloys were isothermally heat treated at different temperatures. The thermal properties, microstructure and magnetic properties of the samples were investigated by differential scanning calorimetry (DTA), X-ray diffraction (XRD), transmission electron microscopy (TEM) and vibrating sample magnetometer (VSM) The results show that the thermal stability of Fe80Zr10B10 alloy without Co addition is significantly higher than that of Co addition, while the thermal stability of (Fe1-x Cox) 80Zr10B10 (x = 0.1, 0.2, 0.3) alloys is similar. The crystallization process of Fe80Zr10B10 and Fe72Co8Zr10B10 alloy is similar. The crystallization process of Fe64Co16Zr10B10 and Fe56Co24Zr10B10 alloy is similar. The coercive force (Hc) of the four alloys first increased and then decreased, reaching the maximum at 873 K.
