(Fe_(1-x)Co_x)_(80)Zr_(10)B_(10)(x=0,0.1,0.2,0.3)合金的热性能、结构和磁性能研究

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。

Thermal Property, Structure and Magnetic Property of (Fe1-xCox)80Zr10B10 (x=0, 0.1, 0.2, 0.3) Alloys

(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.
