摘要：

We　report　a　novel　design　to　fabricate　high　performance　SmCo5　magnet　by　using　Sm2Co7　nanophase　inducing　low-temperature　hot　deformation.　Our　approach　can　reduce　the　hot　deformation　temperature　to　650　degrees　C　from　the　previous　900　degrees　C　to　obtain　nanocrystalline　magnets　with　good　c-axis　texture.　As　a　consequence,　a　giant　coercivity　of　25.6　kOe　is　achieved　in　the　anisotropic　magnet,　which　is　4　times　the　value　reported　previously.　Ascribed　to　the　large　coercivity,　our　magnet　represents　good　thermal　stability,　which　possesses　a　maximum　magnetic　energy　product　of　10.6　MGOe　at　300　degrees　C,　maintaining　75%　of　that　at　room　temperature.　(C)　2019　Acta　Materialia　Inc.　Published　by　Elsevier　Ltd.　All　rights　reserved.
