The　bulk　nanocrystalline　magnets　of　Nd8.5Fe65.5Ti2ZrNbB22-xNx(x=0-2,　at%)　in　the　rod　form　with　2　mm　diameter　were　prepared　by　copper　mold　suction　casting.　The　effects　of　nitrogen　addition　on　the　microstructure,　room-temperature　and　high-temperature　magnetic　properties,　and　corrosion　resistance　of　the　samples　were　studied.　It　is　shown　that　the　N　addition　can　refine　the　grains,　inhibit　the　formation　of　Nd19Fe68B68　phase,　and　promote　the　formation　of　Nd2Fe14B　permanent　magnetic　phase.　Thus,　the　magnetic　properties,　thermal　stability　and　corrosion　resis-tance　of　the　samples　are　significantly　improved.　The　sample　with　x=1　exhibited　the　best　room-temperature　and　high-temperature　magnetic　properties,　and　the　best　corrosion　resistance.　As　compared　to　the　sample　with　x=0,　the　intrinsic　coercivity　iHc,　the　remanence　Br　and　the　maximum　energy　product　(BH)max　of　the　sample　with　x=1　at　room　temperature　increased　by　70.6%,　14.6%　and　100.0%,　respectively.　At　the　same　time,　in　the　temperature　range　of　25-180℃,　the　absolute　values　of　the　temperature　coefficients　α　and　β　for　the　remanence　and　coercivity　decrease　by　36.1%　and　19.7%,　respectively.　The　flux　irreversible　loss　in　the　temperature　range　of　25-250℃　increases　from　-30.8%/K　for　the　sample　with　x=0　to　-19.6%/K　for　the　sample　with　x=1.　Furthermore,　as　x　increases　from　0　to　1,　the　corrosion　potential　Ecorr　increases　from　-0.979　V　to　-0.784　V,　and　the　corrosion　current　density　Icorr　decreases　from　1.054×10-4　A/cm2　to　1.736×10-5　A/cm2.　©　2020,　Materials　Review　Magazine.　All　right　reserved.
