In this study, we successfully fabricated FeZrCoMoWB and NiNb.Ta. amorphous fibers (AFs) using the melt-extraction method. This method ensured a rapid cooling, uniform quality, minimal defects, and superior performance. Magnetic property analysis revealed that the Fe-based AFs exhibited a single-slope magnetization curve characteristic of paramagnetic or diamagnetic materials, while the Ni-based AFs displayed a rectangular curve with low magnetic hysteresis, typical of ferromagnetic materials. The axial saturation magnetization of as-prepared Ni-based AFs is ~1.5 × 10 emu/g, with a coercivity of about 85 Oe. The statistical analysis of tensile tests indicated that Ni-based AFs possess a higher fracture threshold of 2440 ± 199 MPa and a reliability of 14.7, demonstrating greater material safety and suitability for high-performance applications. As opposed to Ni-based AFs, Fe-based AFs present a fracture threshold and of 1582 ± 692 MPa and a reliability 4.2. Moreover, under cyclic loading conditions, Ni-based AFs exhibited less residual deformation and superior elastic recovery with a fracture strength of 2800 MPa. These findings highlight the potential of Ni-based AFs for advanced engineering applications, particularly where high strength, durability, and excellent magnetic properties are required, paving the way for their integration into next-generation technologies.
在本研究中，我们采用熔体萃取法成功制备了FeZrCoMoWB和NiNbTa非晶纤维（AFs）。该方法确保了快速冷却、质量均匀、缺陷最少且性能优异。磁性分析表明，铁基非晶纤维呈现出顺磁性或抗磁性材料特有的单斜率磁化曲线，而镍基非晶纤维则显示出具有低磁滞的矩形曲线，这是铁磁材料的典型特征。制备的镍基非晶纤维的轴向饱和磁化强度约为1.5×10 emu/g，矫顽力约为85 Oe。拉伸试验的统计分析表明，镍基非晶纤维具有2440±199 MPa的较高断裂阈值和14.7的可靠性，表明其具有更高的材料安全性和适用于高性能应用的特性。与镍基非晶纤维相反，铁基非晶纤维的断裂阈值为1582±692 MPa，可靠性为4.2。此外，在循环加载条件下，镍基非晶纤维表现出较小的残余变形和优异的弹性恢复，断裂强度为2800 MPa。这些发现突出了镍基非晶纤维在先进工程应用中的潜力，特别是在需要高强度、耐久性和优异磁性的领域，为其融入下一代技术铺平了道路。
