In this study, we examined the optimal pre- and post-annealing conditions for soft magnetic composites (SMCs) using amorphous flake powders produced through ball milling of amorphous Fe-Si-B ribbons, leading to enhanced magnetic properties. The SMCs, which utilized flake powders created via melt spinning, displayed outstanding DC bias characteristics, as well as increased permeability, primarily due to high saturation magnetization and the flaky morphology of the powders. Pre-annealing was performed not only to remove residual stress formed during the melt spinning process but also to improve pulverizing efficiency, which ultimately affected the particle size of the flake powders. Core annealing was performed to reduce core losses and improve permeability by relieving the residual stress generated during the pressing process. As a result, pre-annealing and core annealing temperatures were identified as crucial factors influencing the magnetic properties of the SMCs. We meticulously analyzed the particle size, the morphology of the flake powder, and the magnetic properties of the SMCs in relation to the annealing temperatures. In conclusion, we demonstrated that flake powder SMCs achieved superior soft magnetic properties, including significantly reduced core loss and heightened permeability, through optimal pre- and core-annealing at 370 °C and 425 °C, respectively.

“…In the field of electronics and communications, they are mainly used in switching power supplies, various inverters, common mode inductors, differential mode inductors, switching power supplies, power factor correction (PFC) inductors, various anti-electromagnetic interference (EMI) devices, and noise suppressors. [75] Fe-based amorphous and nanocrystalline alloys have been widely used in electronic devices such as distribution transformers, photovoltaic inverters, wind converters, and vehicle chargers, as shown in Figure 11. [20] Fe-based amorphous transformers have low no-load losses, and the use of Fe-based amorphous transformers of the same capacity is more energy efficient than silicon steel transformers.…”
