摘要：

A　novel　hot　extrusion　method　to　fabricate　anisotropic　nanocrystalline　SmCo5　magnet　was　investigated.　The　results　indicate　that　the　hot-extruded　(HE)　SmCo5　magnet　obtains　a　strong　c-axis　texture　in　perpendicular　to　the　extrusion　direction,　but　the　texture　strength　is　clearly　different　in　different　regions.　The　deformation　degree　plays　a　key　role　in　the　formation　of　c-axis　crystallographic　texture　and　magnetic　anisotropy.　In　surface　region　of　the　HE　magnet,　the　deformation　degree　of　grains　is　the　biggest,　and　the　c-axis　texture　and　remanence　are　the　strongest.　Furthermore,　deformation　mechanism　of　the　HE　SmCo5　magnet　was　preliminarily　discussed.
