摘 要：在高纯氩气保护下使用机械合金化法对原子组成为 Fe₆₀Zr_40-xB_x（x =10、20、30）的混合粉体进行实验，成功地制取了非晶 合金粉。结合 X 射线衍射与 DSC 的分析，认为： Fe₆₀Zr₂₀B₂₀ 和 Fe₆₀Zr₁₀B₃₀ 体系因 B 原子含量较高，使得其非晶化效率及热稳定性都 要高于 B 原子含量较少的 Fe₆₀Zr₃₀B₁₀ 体系。计算得出 Fe₆₀Zr₂₀B₂₀ 和 Fe₆₀Zr₁₀B₃₀ 两个体系的非晶晶化激活能数据分别为 (201.7±58.5) kJ· mol^-1 和（220.3 ±18.1）kJ·mol^-1。

Abstract: The amorphous alloys of Fe₆₀Zr_40-xB_x(x =10、20、30, at%) sys tems were successfully prepared by mechanical alloying under pure ar gon atmosphere. By X-ray diffraction and differential scanning calorime try, it was concluded that because of more B atoms the amorphization ef ficiency and thermo-stability of Fe₆₀Zr₂₀B₂₀ and Fe₆₀Zr₁₀B₃₀ systems were better than Fe₆₀Zr₃₀B₁₀ system. The calculated activation energy of Fe₆₀Zr₂₀B₂₀ and Fe₆₀Zr₁₀B₃₀ were(201.7±58.5) kJ·mol^-1 and (220.3±18.1) k J·mol^-1 respectively.
