摘要：

Nd-Fe-B amorphous powders with a typical composition and those with lower Nd content were prepared by rapid solidification processing. These amorphous powders were consolidated into bulk materials by dynamic compaction using the gun method. The resultant bulk materials retained the amorphous structure in both alloys. The Nd-Fe-B bulk materials with a typical composition were successfully deformed by die upsetting, but the bulk materials of Nd-Fe-B alloys with lower Nd content were not deformed by die upsetting. The metastable Fe3B phase and alpha-Fe phase together with Nd2Fe14B phase that had crystalized during the die upsetting prohibited the bulk materials from the deformation.
