Abstract: Abstract As-sintered multi-main-phase Nd-Ce-Fe-B permanent magnets typically exhibit a higher coercivity than as-sintered single-main-phase Nd-Ce-Fe-B magnets with identical content of Ce. To clarify the microstructural features that are relevant to the coercivity, as-sintered multi-main-phase Nd-Ce-Fe-B… read more here.

DOI: 10.1016/j.jre.2019.05.019
Abstract: Abstract Sintered (Ce, Nd)-Fe-B magnets with high cost performance were prepared by substituting of Ce for Nd with the dual-main phase method. The corrosion behaviors of dual-main phase sintered (CexNd1–x)30Fe69B1 (x = 0.15 wt%, 0.3 wt%) magnets, which were… read more here.

DOI: 10.1016/j.scriptamat.2020.04.047
Abstract: Abstract Massive rare earth oxides inevitably form at high La-Ce substitution, causing inadequate liquid-phase-sintering, direct exchange coupling of ferromagnetic grains, obscure core-shell morphology and severe coercivity degradation of multi-main-phase (MMP) Nd-La-Ce-Fe-B sintered magnets. To fully… read more here.

Abstract: Nd2Fe14B have attracted intensive attentions due to its excellent magnetic properties since 1980s. However, large demands for the expensive rare earth (mainly refers to Nd/Pr/Dy) limit its wider applications. Investigations of Ce-doped Nd2Fe14B have been… read more here.

DOI: 10.1039/d2ra08291h
Abstract: To inhibit the magnetic dilution effect of Ce in Nd–Ce–Fe–B magnets, a dual-alloy method is employed to prepare hot-deformed dual-main-phase (DMP) magnets using mixed nanocrystalline Nd–Fe–B and Ce–Fe–B powders. A REFe2 (1 : 2, where RE is… read more here.
