摘要：

Commercial　NdFeB　powders　mixed　with　DyHx　nanoparticles　are　hot　pressed　and　hot　deformed　into　anisotropic　magnets　by　Spark　Plasma　Sintering　(SPS).　The　hot　deformed　magnet　exhibits　strong　c-axis　crystallographic　texture.　The　coercivity　of　the　magnet　doped　with　1.0　wt%　DyHx　is　increased　by　66.7%,　compared　with　the　magnet　without　DyHx,　while　the　remanence　decreases　only　by　3%.　TEM　observation　shows　that　there　exists　a　continuous　(Nd,Dy)(2)Fe14B　layer　between　Nd-rich　phase　and　NdFeB　main　phase.　(C)　2015　Elsevier　B.V.　All　rights　reserved.
