Processing and characterization of Nd2Fe14B microparticles prepared by surfactant-assisted ball milling

Eco-Friendly Facile Three-Step Recycling Method of (Nd-RE)2Fe14B Magnet Sludge and Enhancement of (BH)max by Ball Milling in Ethanol

“…During milling, the collision between the ball and the (Nd–RE) 2 Fe 14 B particle cracked big crystallites to smaller ones. This crystallite deformation increased the crystal strain and decreased the hyperfine magnetic field . Conclusively, the magnetic properties were increased because of the decreased hyperfine magnetic field (Figure S6).…”

“…This crystallite deformation increased the crystal strain and decreased the hyperfine magnetic field. 30 Conclusively, the magnetic properties were increased because of the decreased hyperfine magnetic field (Figure S6). After ball milling in ethanol, the magnetic moment was enhanced from 102 to 112 emu/g, and the squareness ratio was increased from 0.69 to 0.76.…”

Fabrication and Characterization of Fe16N2Micro‐Flake Powders and Their Extrusion‐Based 3D Printing into Permanent Magnet Form

“…[30] Especially, the recently developed surfactant-assisted ball milling opened up the way to the synthesis of nanoparticles and nanothin flakes. [31][32][33][34][35][36][37][38][39] The latter morphology is especially important for the permanent magnet production, because it is naturally anisotropic by shape. [40] As stated earlier, one of the shortcomings of traditional permanent magnet production route for the Fe 16 N 2 is the sintering at high temperatures (%900 C) where the magnetic phase is ultimately unstable.…”
