Abstract Scope |
Amorphous iron-based magnetic materials used in transformers and inductive devices have helped in energy saving, addressing the global warming crisis by minimizing core loss in these devices. Fe-Si-B alloys are a group of iron-based magnetic materials that possess good magnetic properties such as high permeability and saturation magnetization along with low coercivity. For this research work FeSiB-based magnetic alloys were fabricated via mechanical alloying followed by spark plasma sintering. The effect of milling parameters (duration, BPR, etc.) as well as addition of Copper and Niobium (producing FeSiBCu, FeSiBNb, and FeSiBCuNb) on crystallite size and phase transformation were studied. Moreover, mechanical, and magnetic behavior of the sintered alloys were investigated. Microstructure of the alloys were studied by Scanning Electron Microscopy (SEM) analysis and X-ray Diffraction (XRD) was conducted on milled powders as well as sintered alloys in order to study the phases present before and after the sintering process takes place. |
