摘要
采用单辊快淬法制备Fe40Co40Zr10B9Cu1、Fe40Co40Zr10B9Ge1和Fe40Co40Zr10B9Ag1非晶合金薄带,并对3种合金在不同温度下进行热处理.利用差热分析仪(DTA)和X射线衍射仪(XRD)等测试手段对样品的热稳定性及微观结构进行研究.结果表明:Fe40Co40Zr10B9Cu1、Fe40Co40Zr10B9Ge1和Fe40Co40Zr10B9Ag13种合金的激活能分别为262.4、267.6和252.3 k J/mol,说明Cu元素、Ge元素和Ag元素的添加对合金的热稳定性影响不大,Ge元素的添加最有利于提高合金的热稳定性.3种合金的晶化过程相似:非晶→非晶+α-Fe(Co)→α-Fe(Co)+Zr Co3B2+Fe(Co)3Zr.
Fe40Co40Zr10B9Cu1、Fe40Co40Zr10B9Ge1and Fe40Co40Zr10B9Ag1 amorphous ribbons were prepared by the single roller melt-spinning and annealed at different temperatures. The thermal stability and microstructure were investigated by differential thermal analysis（ DTA） and X-ray diffraction（ XRD）. The results showed that the crystallization activation energies were 262. 4,267. 6 and 252. 3 k J / mol,respectively. The addition of Cu、Ge and Ag elements had not much effect on the thermal stability of the alloys. The crystallization processes of three alloys were similar： amorphous → amorphous ＋ α-Fe（ Co） →α-Fe（ Co） ＋ Zr Co3B2＋ Fe（ Co）3Zr.
