中文摘要：

采用油胺作为表面活性剂，将Sm2Fe17微米粉进行表面活性剂辅助高能球磨（HEBM）4h后，获得厚100—180nm，长2～13μm的纳米片，该纳米片具有织构，晶粒尺寸约8nm。在300—350℃低温范围内，进行低压、短时渗氮，获得Sm：Fe，，N，片状粉末。Sm2Fe17纳米片在350℃、3psi氮气压力下渗氮3h后，矫顽力可达到3．56kOe，晶粒保持纳米尺度不变，且具有（001）织构。

英文摘要：

Sm2Fej7 nano flakes with a thickness of about 100-180 nm and a length of about 2-13 μm have been prepared by oleylamine surfactant-assisted high energy ball milling （HEBM） Sm2Fe17 micro-powders for 4 h. The nano flakes have a texture and its grain size is about 8 nm. Sm2Fe17N3ean be obtained when the nano flakes are nitrided under low pressure for a short time at 300-350 ℃. When the as- synthesized nano flakes nitrided at 350 ℃ for 3 h under 3 psi nitrogen atmosphere, eoercivity is 3.56 kOe, grain size is still in nanoscale and （001） texture is still retained.
