Propulsion and PWR Rapid Response Research and Development (R&R) Support: Delivery Order 0030: Study of Hot Deformation of Nanocomposite Rare Earth Magnets

Abstract

High performance bulk anisotropic nanograin composite Nd2Fe14B/Fe and Nd2Fe14B/Fe-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, (BH)max could reach 45-55 MGOe. In addition, bulk anisotropic hybrid nanograin Pr2Fe14B/PrCo5 magnets with improved thermal stability were synthesized, and nanograin Sm2(Co, Fe) 17Fe-Co magnets were studied.
