2　∶　17　type　Sm(CoFeCuZr)z　sintered　permanent　magnets　are　widely　used　in　many　important　fields　such　as　aerospace,　military　technology,　and　new　energy　technology　due　to　their　good　magnetic　properties　and　excellent　thermal　stability.　The　preparation　technology　of　the　2　∶　17　Sm(CoFeCuZr)z　sintered　permanent　magnet　is　based　on　the　traditional　powder　metallurgy　method.　During　the　last　decades,　numerous　research　projects　focusing　on　preparation　technology　have　been　carried　out　to　develop　high-performance　magnets　around　the　world.　Specifically,　quite　a　few　novel　processing　techniques　such　as　strip-casting,　hydrogen　decrepitation,　jet　milling　and　secondary　phase　doping　have　been　gradually　applied　in　recent　years,　which　are　beneficial　to　the　improvement　of　overall　magnetic　performance　of　the　magnet.　Based　on　the　preparation　process　of　2　∶　17　Sm　(CoFeCuZr)z　sintered　permanent　magnets,　this　paper　introduces　the　research　progress　of　magnets　in　as-cast　alloy,　pulverizing　process,　doping　process,　and　heat　treatment　process,　summarizes　the　effects　of　different　preparation　processes　on　the　microstructure　and　magnetic　properties　of　magnets,　and　evaluates　the　application　of　the　new　process　in　the　preparation　of　high-performance　Sm(CoFeCuZr)z　permanent　magnets.　©　2024　Editorial　Office　of　Chinese　Rare　Earths.　All　rights　reserved.
