| 简介 |
A rare-earth iron-based magnet with self-recoverability is provided and includes a plurality of segments, wherein the segments each include a matrix having a microstructure in which rare-earth iron-based aligned magnetic powders of at least one kind are solidified by a cross-linking reaction phase and also in which the cross-liking reaction phase and a viscous deformation phase resulting from on a viscosity flow are chemically bound to each other between the magnetic powders, and wherein while the inner and outer circumferential surfaces of the segments are constrained, the fracture surfaces of the segments, and also the segments on a needed-basis, are mutually aggregated and rigidified together by taking advantage of self-recovery function based on viscous deformation caused by heat and external force and also on cross-linking reaction. |
