摘要：

Phase　and　texture　evolution　of　the　hot-deformed　Sm(Co,Fe,Cu,Zr)z　magnet　prepared　by　spark　plasma　sintering　(SPS)　have　been　investigated.　The　effects　of　hot　deformation　temperature　and　height　reduction　on　the　phase　structure　and　magnetic　properties　of　the　magnet　were　studied.　The　results　show　that　with　90%　height　reduction　at　900　°C,　the　hot-deformed　magnet　with　TbCu7　structure　obtains　an　obvious　c　-axis　texture.　However,　with　increasing　hot　deformation　temperature,　some　1:7H　phases　decompose　into　2:17R,　1:5H,　and　Zr-rich　particle　phases　in　the　hot　deformation　process.　The　hot-deformed　magnet　with　85%　height　reduction　possesses　a　remanence　(　Mr　)　of　6.9　kG,　which　is　higher　than　that　of　the　isotopic　precursor.　©　1965-2012　IEEE.
