Hot-pressed and hot-deformed nanocomposite (Nd,Pr,Dy)/sub 2/Fe/sub 14/B/(alpha)-Fe-based magnets

Fully dense isotropic and anisotropic (Nd,Pr,Dy)/sub 2/Fe/sub 14/B/(alpha)-Fe nanocomposite magnets have been successfully prepared by a hot press and hot deformation technique using melt-spun precursors. For the fully dense, hotdeformed, anisotropic nanocomposite (Nd,Pr,Dy)/sub 2/Fe/sub 14/B/(alpha)-Fe-based magnets containing ~4 vol% and ~11 vol% (alpha)-Fe, the maximum energy products have reached 31 and 24 MGOe, respectively. At the time of proofreading for this paper, 42 MGOe has been reached for the nanocomposite magnets with ~4 vol% (alpha)-Fe.
