Dy2fe14b coercivity

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.

WebMar 1, 2024 · ABSTRACT. We investigated La-coated Nd 2 Fe 14 B thin film magnets by scanning/transmission electron microscopy to clarify the coercivity enhancement mechanism in Nd-Fe-B permanent magnets. The coercivity of La-coated film magnets was increased from 8.5 to 15 kOe by post-annealing. The fcc-LaO x layer was epitaxially … 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. WebDy/Tb resources.
