    摘要:

    采用單輥快淬法制備(Fe1-xCox)80Zr10B10(x=0,0.1,0.2,0.3)非晶合金，并對4種合金在不同溫度下進行等溫?zé)崽幚?。利用差熱分析儀(DTA)，X射線衍射儀(XRD)，透射電鏡(TEM)和振動樣品磁強計（VSM）等測試手段對樣品的熱性能、微觀結(jié)構(gòu)及磁性能進行研究。結(jié)果表明，未添加Co元素的Fe80Zr10B10合金的熱穩(wěn)定性明顯高于添加Co元素的合金，而(Fe1-xCox)80Zr10B10(x=0.1,0.2,0.3)合金的熱穩(wěn)定性相差不大。Fe80Zr10B10和Fe72Co8Zr10B10合金的晶化過程相似；Fe64Co16Zr10B10和Fe56Co24Zr10B10合金的晶化過程相似。4種合金的矯頑力（Hc）呈現(xiàn)先上升后下降的趨勢，在873 K達到最大值。

    Abstract:

    (Fe1-xCox)80Zr10B10 (x=0, 0.1, 0.2, 0.3) amorphous ribbons were prepared by the single roller melt-spinning and they are isothermally annealed at different temperatures. Thermal properties, microstructures and magnetic properties of the samples were investigated by differential thermal analysis (DTA), X-ray diffraction (XRD), transmission electron microscopy (TEM) and vibrating sample magnetometer (VSM). The results show that the thermal stability of the Co-free alloy is higher than that of the Co-containing alloys. However, there is little difference in the thermal stability of (Fe1-xCox)80Zr10B10 (x=0.1, 0.2, 0.3) alloys. The crystallization processes of Fe80Zr10B10 and Fe72Co8Zr10B10 alloys are similar. The crystallization processes of Fe64Co16Zr10B10 and Fe56Co24Zr10B10 alloys are similar. Coercivity (Hc) of the four alloys all increase firstly and then decrease. At 873 K, Hc all reaches the maximum.
