This study aims to determine the effect of addition of a small quantity of Si on the formation of nanocrystalline structure in rapidly cooled Fe-Co-B alloys. As part of the work, the following alloys were produced using a method involving the forcing of each respective liquid alloy into a copper mold: Fe₆₅Co_11−xB₂₀Si_xZr₂Hf₂ (where: x = 0; 0.25; 0.5; 0.75; 1). Analysis of recorded X-ray diffraction patterns confirmed that a nanocrystalline structure was obtained in the alloys. The intensity of the diffraction reflections was found to change with changing Si content. The Fe₂₃B₆ crystalline phase was present in the volume of each alloy. This phase has soft magnetic properties. The presence of the Fe₂₃B₆ phase was confirmed by measurements of the magnetic polarization of saturation as a function of temperature.

这项研究旨在确定在快速冷却的Fe-Co-B合金中添加少量Si对纳米晶体结构形成的影响。作为工作的一部分，使用涉及将每种液态合金强制压入铜模的方法生产以下合金：Fe ₆₅ Co _{11- x} B ₂₀ Si _x Zr ₂ Hf ₂（其中：x = 0; 0.25; 0.5; 0.75; 1）。对记录的X射线衍射图谱的分析证实了在合金中获得了纳米晶体结构。发现衍射反射的强度随Si含量的变化而变化。铁₂₃ B ₆每种合金的体积中都存在结晶相。该相具有软磁特性。Fe ₂₃ B ₆相的存在通过测量饱和磁极化强度随温度的变化来确定。
