WebMar 1, 2008 · The configuration of Dy 2 Fe 14 B as the surface and Nd 2 Fe 14 B as the bulk is expected to raise the coercivity while maintaining the energy product of Nd–Fe–B magnets. 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.

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. 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. cylinder inspection requirementsWebThe structural parameters of the Dy 2 Fe 14 B unit cell are as follows: a = b = 8.776 Å, c = 11.945 Å, Dy (4f) = (0.268, 0.268, 0), Dy (4g) = (0.146, −0.146, 0), Fe (16 k1) = (0.224, −0.435, 0.126), Fe (16k 2) = (0.037, 0.359, 0.175), Fe (8 j1) = (0.098, 0.098, 0.201), Fe (8 j2) = (0.317, 0.317, 0.246), Fe (4e) = (0.5, 0.5, 0.384), Fe (4c) = … cylinder in spherical coordinates
