“…These components were mixed in proportion and then combined with spherical Fe-based metallic glass powder with a diameter of 5-75 µm using high-energy ball milling in a planetary ball mill for 12 h. The powder we used in the study was provided by Beijing ZJLG Amorphous Technology Co., Ltd., Beijing, China. The composition of the Fe-based amorphous alloy used is shown in ref [23]. A dispersed and stabilized metallic glass powder slurry with a solid content of 50% was obtained [23].…”

Fe-based metallic glasses are amorphous alloys with high strength, high hardness, and excellent corrosion resistance; however, the immaturity of processing methods has prevented their wide application in industrial production. Fe-based metallic glass parts were manufactured employing pneumatic injection additive manufacturing in this study. An evenly dispersed and stable Fe-based metallic glass powder slurry with a solids content of 50% was prepared firstly. Then the Fe-based metallic glass parts were printed. The printed parts were dried, debinded, and sintered for strengthening. The deformations of the printed parts and sintered parts relative to the original model were then analyzed by a 3D scanning reconstruction method. The slightly average bulging and sunken deformation of the printed parts and sintered parts confirmed the good printing accuracy of the pneumatic injection manufacture system. The effects of the sintering temperature and holding time on the properties of the sintered parts were studied. For a sintering temperature of 580 • C and holding time of 1 h, the surface quality of the sintered parts was better. The sintering of 3D-printed Fe-based metallic glass parts was preliminarily realized in this study, and the feasibility of preparing Fe-based metallic glass using pneumatic injection additive manufacture was verified.

“…Another attractive 3D processing was the direct ink writing (DIW), the most obvious feature of this technology was that it was printed on the basis of extruded concentrated slurry (Truby and Lewis, 2016), so long as the material that could be adjusted into slurry could be formed in DIW, such as polymer slurry (Zhang et al, 2021a), metal slurry, and cell slurry (Yuk and Zhao, 2018). It had also been studied to process magnetic materials, Fe-based metallic glass slurries were printed with DIW in the work Wu et al (Wu et al, 2018), and alkaline environment was not conducive to the wetting and stable dispersion. Amir et al evaluated DIW as a technique for creating parts using nickel-based superalloy 625, which maintain high fatigue resistance (Mostafaei et al, 2018).…”

Fe-based amorphous alloy has excellent soft magnetic properties; traditionally, Fe-based amorphous alloy such as soft magnetic devices was fabricated by insulation enveloping and suppression molding methods. In this process, the aging of organic envelope materials and the crystallization of Fe-based amorphous alloy were usually occurring, accompanying with low magnetic induction and poor mechanical properties. The direct ink writing (DIW) technique can make complex-shaped parts and needs no heating treatment after forming, which can avoid the effect of traditional molding process. In the present study, varying mass fraction FeSiB/EP composite parts were prepared by the DIW technique with the Fe-based amorphous alloy powder and epoxy resin, in which microscopic morphology, magnetic properties, and mechanical properties of FeSiB/EP soft magnetic composites were studied. The results indicate that the slurry with iron powder mass fraction of 92.3, 92.6, and 92.8 wt% has good printing performance and self-support ability, which is suitable for DIW. The density of the printed parts is about 4.317, 4.449, and 4.537 g/cm3, which is almost similar with the iron powder. The tensile strength and elongation of printing parts are significantly improved compared with the pure epoxy resin. From the photos of microscopic morphology of printing parts, it can be seen that FeSiB powders are evenly dispersed in EP, no pores, and defects, with the proportion increasing of powders; the insulation coating thickness decreases; and the magnetic performance improves. The optimal sample is 92.8 wt% FeSiB/EP, in which saturation magnetic induction strength is 137.9759 emu/g and coercivity is 4.6523 A/m.
