Comparative study of tensile properties and magnetic properties for Nb-doped Fe-based wires
Herein, the comparative study of tensile and magnetic properties of Fe-based wires formed by rotated-dipping process before and after Nb-doping has been reported. In which, the phase composition, crystallization temperature, surface and fracture morphology, and magnetic performance are respectively...

Herein, the comparative study of tensile and magnetic properties of Fe-based wires formed by rotated-dipping process before and after Nb-doping has been reported. In which, the phase composition, crystallization temperature, surface and fracture morphology, and magnetic performance are respectively investigated by X-ray diffraction (XRD), differential scanning calorimetry (DSC), scanning electron microscope (SEM) and Physical Property Measurement System (PPMS), respectively. Further, the experimental results indicate that the Nb-doped Fe-based wires show an amorphous state, uniform, and continuous, with excellent glass forming ability (GFA) and thermal stability. The saturation magnetization Ms and remanent magnetization Mr decrease owing to Nb-doping, while the coercivity Hc shows an increasing trend with the rising of Nb-doping, reaching 33.0 Oe. The tensile deformation process of Nb-doped Fe-based wires is mainly elastic deformation, reflecting the brittle fracture characteristics. While the Nb-doping can effectively enhance the tensile strength Rm of Fe-based wires, and the Rm of FeSiBNb3 wires exhibits the maximum value of 3.58 GPa. Moreover, the fracture morphology takes on the massive shear bands, and the fracture angles are about 45°, there are also some vein-shaped patterns and molten drops, even the fracture reliability analysis based on the statistical theory of Weibull mechanics indicates that the Nb-doped Fe-based wires possess an obviously improved fracture reliability. Therefore, it can be concluded that the Fe-based wires with improved tensile and magnetic properties as the candidates are adopted for potential electromagnetic and mechanical engineering applications. |
