WebConclusions. We have established the disproportionation of the Dy 2 Fe 14 B compound in hydrogen at a temperature close to 960 K and under an initial hydrogen pressure of 5.2 MPa into dysprosium hydride, iron, and iron boride. Recombination in a vacuum occurs after heating to 980 K in several stages. Download to read the full article text. WebFeb 1, 1986 · For Nd 70 Cu 30-doped magnets, the increment of coercivity is only 1.2 kOe. Meanwhile, Dy 70 Cu 30-doped and (Nd 0.5 Dy 0.5) 70 Cu 30-doped magnets show an almost identical enhancement of coercivity of about 4.4 kOe. Importantly, the latter magnet shows a beneficial effect of reducing the usage of Dy from 1.6 wt% to 0.8 wt%. TEM …
Microstructure and coercivity in La-coated Nd2Fe14B thin films
In this work, we synthesize Nd 2 Fe 14 B nanostructures with tunable magnetic properties through surfactant-assisted high energy ball milling (SAHEBM) process, achieving prominently enhanced coercivity by forming non-magnetic layers as grain boundary phase.

Our strategy is based on the fact that coercivity is controlled by the nucleation of reverse domains at the surface and not by the bulk magnetocrystalline anisotropy. WebApr 29, 2024 · It can be seen that the intrinsic coercivity first increases with Zr substitution, from 62 kA·m −1 (Zr-free) up to highest value of 945 kA·m −1 with 2 at% Zr, and then decreases with further addition of Zr. This indicates that a certain amount of Zr addition favors the coercivity of Pr 9.5 Fe 84 B 6.4 P 0.1 alloy. switching to ohio drivers license
