High performance bulk anisotropic nanograin composite Nd2Fe14BFe and Nd2Fe14BFe-Co magnets were successfully synthesized using hot compacting blended Nd-Fe-B and Fe-Co powders or coated ND-Fe-B powders followed by a subsequent hot deformation. Using both techniques, BHmax could reach 45-55 MGOe. In addition, bulk anisotropic hybrid nanograin Pr2Fe14BPrCo5 magnets with improved thermal stability were synthesized, and nanograin Sm2Co, Fe 17Fe-Co magnets were studied.
