In this study, Fe-based amorphous powder with a composition of Fe₄₀ Ni₂₅Zr₁₀Si₁₀B₁₅ (compound Q) was prepared by a partial replacement of Fe with Zr and Ni in a Fe₇₅Si₁₀B₁₅ (compound P) via a mechanical alloying route. This substitution led to a decrease in amorphization time and consequently a significant improvement in thermal stability. The structure and thermal properties of the prepared powders were investigated by x-ray diffraction (XRD) pattern and differential scanning calorimetry (DSC), respectively. XRD and DSC results revealed that complete amorphization is achieved after 50 h of milling and glass forming ability width (ΔT_x) increases from 50°C to 66°C by substitution of Fe with Zr and Ni in compound P. Magnetic properties of the samples, investigated by vibrating sample magnetometry, indicated that in spite of a negligible decrease in saturation magnetization (M_s) by Fe replacement with Zr and Ni, the coercivity (H_c) shows a positive response to this change as a soft magnetic material, decreasing from 35 Oe to 15 Oe.

机械合金化多组分铁基非晶合金中Zr和Ni同时置换Fe的作用

在这项研究中，通过在Fe ₇₅ Si ₁₀ B ₁₅中用Zr和Ni置换Fe来制备组成为Fe ₄₀ Ni ₂₅ Zr ₁₀ Si ₁₀ B ₁₅（化合物Q）的Fe基非晶粉末。（化合物P）通过机械合金化途径。这种取代导致非晶化时间的减少，因此热稳定性显着提高。分别通过X射线衍射（XRD）图和差示扫描量热法（DSC）研究了所制备粉末的结构和热性能。XRD和DSC结果表明，在研磨50小时后，通过用化合物P中的Zr和Ni取代Fe，玻璃形成能力的宽度（ΔT _x）从50°C增加到66°C，实现了完全非晶化。样品，通过振动样品磁力分析法进行了研究，结果表明，尽管用Zr和Ni代替Fe可使饱和磁化强度（M _s）降低到可以忽略不计，但矫顽力（H _c）作为一种软磁性材料，对该变化表现出积极的响应，从35 Oe降至15 Oe。
