Feb 14, 2008 · 1.. IntroductionA possible large scale, future application of the HD process could be in the recycling of SmCo 5, Sm 2 (Co,FeCu,Zr) 17 and NdFeB-type magnets. Recycling NdFeB-type magnets by this means has been proposed by Rivoirard et al. [1] and by Zakotnik et al. [2] and these workers reported very encouraging results on the production of anisotropic powder from degassed HD powder obtained ... The platelet-shaped grains with c-axis alignment, which are the typical morphology of textured hot-deformed magnets, are observed in the SE-SEM image of Fig. 3 (a). Notably, two different morphology regions, i.e. well-aligned and misaligned, are observed in the bottom and top parts of the SE-SEM image.
