Soft magnetic composites (SMCs) possess promising electromagnetic characteristics and attract intense research and application interest in the engineering community. Fabrication of composites with customized architecture is feasible due to the recent advances in additive manufacturing (AM) techniques. The systematic progress of computational optimization has opened up the possibility of devising such structures. This article presents newly structured SMCs which can recently be possible by AM. The effective permeability and eddy current losses are studied in comparison to those properties of traditionally fabricated SMCs. With this hollow inclusion arrangement, for the same iron volume fraction, the effective permeability can be greatly enhanced (more than tenfold) while the eddy current losses decrease considerably. For the same magnetic property, we save iron material, make the composite lighter, and benefit from a lower level of eddy current losses with the hollow configuration.

“…The hysteresis loss strongly depends on the coercivity of the alloy and the density of SMPCs [5,8,13]. Several researchers have tried to reduce the coercivity of the Fe-6.5 wt%Si alloy by doping Ti and Co [14,15]. Doping moderate specific elements may improve the internal microstructure of Fe-6.5 wt%Si alloy to reduce the coercivity.…”

The effect of different particle size distribution of Fe-6.5 wt%Si powder on the microstructure and soft magnetic properties of the corresponding soft magnetic powder cores (SMPCs) was investigated. By optimizing particle size distribution, the density of SMPCs increased and the total core loss significantly decreased. According to the result of loss separation, density of SMPCs is inversely proportional to hysteresis loss, while with increasing the content of the fine particles, the eddy current loss significantly decreased. It was found that with magnetic powder of particle size-grading as 10%, 10%, 60%, and 20% for particles with size between −75 to +38, −38 to +23, −23 to +13, and −13 μm, respectively, the Fe-6.5 wt%Si SMPCs exhibit optimal comprehensive magnetic performances with the effective permeability of about 60, the percent permeability at 100 Oe is up to 70%, and the lowest core loss of 553 mW/cm3.

“…Adding transition metal can greatly improve and adjust their microstructure and performance, such as Nb, V, Cr, Ti, W and Al element. Nb and W are the most effective elements which can refine the grain size during annealing treatment (Li et al, 2017;Alleg et al, 2012;Silveyra and Illekova, 2014;Ji et al, 2018;Ma et al, 2016;Botta et al, 2014;Xu et al, 2018;Liu et al, 2014;Wang et al, 2018;Yang et al, 2013;Liang et al, 2018;Stepanov et al, 2019;He et al, 2014;Duan et al, 2019;Murugaiyan et al, 2018;Takeuchi and Inoue, 2005). The addition of V can improve the amorphous forming ability and the bending ductility of the alloys (Ji et al, 2018).…”

A series of Fe40Co40Zr8M2B10 (M=Nb, V, Cr, Ti, W, Al) alloys were prepared using melt-spinning. The thermal curve, structure and magnetic property of alloys are examined. Because of different negative heat of mixing between elements, only Fe40Co40Zr8M2B10 (M=Nb, V, Cr, Ti) alloys form amorphous structure. These amorphous alloys are annealed at different temperatures under vacuum conditions. The crystallization processes of four amorphous alloys are similar. In the primary stage of crystallization process, only α-Fe (Co) phase precipitates and Co element mainly distributes in the residual amorphous. For the four alloys after annealing at 550°C, there is a few differences in saturation magnetization (Ms) and coercivity (Hc) due to their different microstructures.
