Spark　plasma　sintering　technique　had　been　applied　to　prepare　bulk　isotropic　and　anisotropic　nanostructured　Nd-Fe-B　permanent　magnets　via　hot　pressing　and　subsequent　hot　deformation　process.　Influences　of　processing　conditions　and　deformation　height　reduction　on　the　structure　and　magnetic　properties　of　the　magnets　were　investigated.　For　the　hot　deformed　magnet　with　80%　height　reduction,　XRD　patterns　of　the　anisotropic　magnets　show　dominant　(00l)　diffraction　peaks　indicating　evident　c-axis　crystallographic　alignment　in　the　magnet.　Under　the　optimal　processing　conditions,　the　anisotropic　magnet　with　80%　height　reduction　exhibits　excellent　magnetic　properties　as　remanence　(B(r))　of　1.492　T,　coercive　force　(H(ci))　of　1004　kA/m,　and　the　maximum　energy　product　[(BH)(max)]　of　400　kJ/m(3),　which　are　among　the　highest　reported　magnetic　properties　of　nanostructured　Nd-Fe-B　permanent　magnets.　(C)　2010　American　Institute　of　Physics.　[doi:　10.1063/1.3339067]
