| 英文摘要 | LaCe-based sintered magnets with different microstructural features and distinct rare earth elemental distribution were designed by dual-alloy method. The sample prepared by fine LaCe-containing powder and coarse LaCe-free powder possesses higher remanence (similar to 13.41 kGs), whereas another sample prepared by fine LaCe-free powder and coarse LaCe-containing powder possesses higher coercivity (similar to 5.67 kOe). Additionally, these samples are with the same nominal compositions and their elemental distribution features are obviously different in matrix grains respectively. Their remanence difference is mainly affected by the saturation magnetization difference caused by the distribution variation of the rare earth elements at the matrix phase. The coercivity difference is affected by the component of the grain boundary phase between the adjacent grains and the distribution variation of the rare earth elements at the matrix phase. These findings may provide a new prospect for the utilization of LaCe misch-metal in 2:14:1-type permanent magnets. (C) 2020 Published by Elsevier B.V. on behalf of Chinese Society of Rare Earths. |
