Abstract Scope |
Co-based metal amorphous nanocomposites soft magnetic materials (MANCs) exhibit excellent magnetic and mechanical properties with tunable characteristics through magnetic field and strain annealing methods, making it promising for applications such as inductors and current transformers at elevated temperature. Of great interest for space and other environments are high temperature performance and thermal stability. In this project, the thermal stability of Co-Fe2.3Mn2.3Nb4Si2B14 at elevated temperature has been investigated. The crystallization kinetics of primary and secondary crystallization are investigated by differential scanning calorimetry (DSC), and activation energy are calculated by Kissinger method. Transmission electron microscopy (TEM) and electron backscatter diffraction (EBSD) are performed to investigate the microstructural evolution during annealing at elevated temperature. The magnetic properties after annealing are measured by vibrating-sample magnetometer (VSM). The results indicated that Co-Fe2.3Mn2.3Nb4Si2B14 exhibits excellent thermal stability and magnetic properties, indicating it is promising for magnet applications at elevated temperature. |
