Bulk rapidly solifidied magnetic materials |
摘要 |
Bulk rapidly solidified magnetic materials having a density of greater than 90%, a thickness of at least 250 microns, and preferably a low oxygen content, are produced by a liquid dynamic compaction process which, depending upon the chosen operating conditions, can yield materials ranging from crystalline to partially crystalline to amorphous. The materials so produced are directly useful, i.e. without having to be reduced to a powder and consolidated into a shape, to produce permanent magnets. When the materials are amorphous, they can be directly used as soft magnetic materials and for other purposes
