    • 专利摘要:
    The present patent aims to present a new method for the powder metallurgical manufacture of magnets (applicable especially to the manufacture of magnets containing rare earths). The novelty of the method lies in the use of some form of electrical consolidation (such as the so-called electric resistance sintering, sre, or the so-called consolidation by electric discharge, cde, but not necessarily one of these) in substitution of the conventional route of pressing cold sintered, usually used. This achieves: (1) combining the compaction/sintering stages, significantly shortening their duration and reducing the magnitude of the working pressures, (2) carrying out the magnetic alignment, pressing/sintering, thermal treatment and magnetization steps in the same matrix, and (3) make unnecessary the use of protective atmospheres during the sintering process.
