This research aims to create suitable Fe-based soft magnetic amorphous alloys for the 3D printing of motor parts, based on the iron-silicon-boron (Fe-Si-B) ternary system. The goal is to enhance the glass forming ability (GFA) to achieve a fully amorphous structure in 3D-printed parts, which is expected to improve motor efficiency by increasing magnetic softness and reducing energy losses. This is achieved through adjusting the compositions while maintaining competitive soft magnetic properties.
For increasing GFA, the critical thickness of samples was examined. The structure and thermal behavior of the samples were characterized using XRD, DSC, and DTA. Magnetic properties were determined by VSM. The hysteresis loops were measured in the low and medium frequencies.
The eutectic zone of the Fe-Si-B system was experimentally determined. Evaluating quaternary and quinary component alloys involved studying the effects of elements on GFA and magnetic properties.
