内容説明
These papers provide an interesting collection of contributions on fundamental magnetic behaviour, microstructural studies, processing methods and applications of rare earth, iron-rich, high performance permanent magnets. The remarkably versatile nature of the Nd-Fe-B-type alloys with respect to magnet processing is very evident in these proceedings. Thus there are papers which describe the production of magnets by the die-upset-forging of melt-spun ribbon, by cold-compaction of melt-spun-ribbon with soft metals, by mechanical alloying and by hot working of cast material. Work is also reported on the production of new permanent magnets from melt-spun material based on the alloys Nd 4 Fe 78 B 18 and SmFe 11.5 Ti 1.04 . Both these alloys look promising and the former appears to be close to commercial exploitation.
