Nanocrystalline　SmCo5　magnet　has　been　investigated　for　many　years　due　to　its　extraordinary　high　anisotropy　filed　as　well　as　coercivity.　Therefore,　producing　an　anisotropic　structure　SmCo5　magnet　through　hot　deformation　has　attracted　considerable　interest　in　order　to　acquire　higher　magnetic　performance.　Nevertheless,　most　of　precursors　magnets　are　crystal　matrix　before　hot　deformation,　while　amorphous　matrix　can　maximize　the　retention　of　fine　grains　and　control　grains　growth,　which　will　definitely　benefit　the　magnetic　performance!1!.　In　this　study,　we　report　a　novel　approach　to　synthesize　bulk　anisotropic　SmCo5　nanocrystalline　magnets　from　SmCo5　amorphous　precursor.　©　2018　IEEE.
