“…Soft magnetic materials, in contrast to hard magnetic materials, should have a minimum coercivity, minimum hysteresis losses, high saturation magnetization, and maximum values of permeability. At the moment, the most widely used soft magnetic materials are pure iron [39,104], electrical steels based on an Fe-Si system, permalloys [8], soft magnetic ferrites such as Fe 2 O 3 , Fe 3 O 4 [66,105,106], NiZn [101], and amorphous and nanocrystalline alloys based on cobalt and iron [8,33,[107][108][109][110].…”

Additive manufacturing is a very rapidly developing industrial field. It opens many possibilities for the fast fabrication of complex-shaped products and devices, including functional materials and smart structures. This paper presents an overview of polymer 3D printing technologies currently used to produce magnetic materials and devices based on them. Technologies such as filament-fused modeling (FDM), direct ink writing (DIW), stereolithography (SLA), and binder jetting (BJ) are discussed. Their technological features, such as the optimal concentration of the filler, the shape and size of the filler particles, printing modes, etc., are considered to obtain bulk products with a high degree of detail and with a high level of magnetic properties. The polymer 3D technologies are compared with conventional technologies for manufacturing polymer-bonded magnets and with metal 3D technologies. This paper shows prospective areas of application of 3D polymer technologies for fabricating the magnetic elements of complex shapes, such as shim elements with an optimized shape and topology; advanced transformer cores; sensors; and, in particular, the fabrication of soft robots with a fast response to magnetic stimuli and composites based on smart fillers.

“…Amorphous materials have unique structural properties that increase strength, magnetic softness, and corrosion resistance. Amorphous alloys, especially those based on iron, are widely used as magnetically conductive elements in electrical engineering due to their high magnetic softness [2][3][4][5][6][7]. Industrial production of such materials involves casting into water-cooled copper molds, melt spinning, and thermoplastic molding.…”

Laser powder bed fusion (LPBF) is a prospective and promising technique of additive manufacturing of which there is a growing interest for the development and production of Fe-based bulk metallic glasses and amorphous–nanocrystalline composites. Many factors affect the quality and properties of the resulting material, and these factors are being actively investigated by many researchers, however, the factor of the inert gas atmosphere used in the process remains virtually unexplored for Fe-based metallic glasses and composites at this time. Here, we present the results of producing amorphous–nanocrystalline composites from amorphous Fe-based powder via LPBF using argon and helium atmospheres. The analysis of the microstructures and phase compositions demonstrated that using helium as an inert gas in the LPBF resulted in a nearly three-fold increase in the amorphization degree of the material. Additionally, it had a beneficial impact on phase composition and structure in a heat-affected zone. The received results may help to develop approaches to control and improve the structural-phase state of amorphous–nanocrystalline compositional materials obtained via LPBF.

“…Thus, low coercivity is achieved with a fully amorphous phase present in the material. [ 1 ] Introducing nanocrystalline phases into an amorphous matrix provides higher saturation magnetization and higher permeability ( Figure ), especially in Fe‐based ferromagnets. [ 2 ] Their exceptional soft‐magnetic properties allow them to be utilized as a magnetic core material in electromagnetic systems to increase their efficiency by lowering the energy losses considerably for eddy currents.…”

Soft‐Magnetic Behavior of Fe‐Based Nanocrystalline Alloys Produced Using Laser Powder Bed Fusion

Herein, an extensive experimental study is presented on the influence of the major process parameters of the laser powder bed fusion (LPBF) technique on the bulk density and soft‐magnetic properties of Fe‐based bulk metallic glasses (BMGs). For this purpose, 81 samples are manufactured using the combinations of different process parameters, that is, layer thickness (t: 50–70 μm), laser power (P: 70–130 W), laser scan speed (v: 900–1100 mm s−1), and hatch spacing (h: 20–40 μm). High bulk density (≥99%) is achieved utilizing low P and v combined with low h and t in order to decrease energy input to the powder, preventing cracks associated with the brittle nature of BMGs. Furthermore, it is indicated that h = 30 μm and v = 1000 mm s−1 play a determining role in acquiring high saturation magnetization (≥200 Am2 kg−1). Due to the laser scanning nature of the process, two distinct microstructures evolve, melt‐pool (MP) and heat‐affected zone (HAZ). According to thermal modeling performed in this study, laser power has the major effect on the thermal development in the microstructure (thermal gradient evolved between the two hatches and the cooling rate from MP through HAZ).
