摘要
在深入探讨三元稀土铁基化合物Ｓｍ２Ｆｅ１７Ｎｙ的制备工艺和磁性能的基础上，确定熔炼母合金、渗氮、球磨及粘结等制备优化的Ｓｍ２Ｆｅ１７Ｎｙ磁体具体工艺过程的技术参数．制取了居里温度Ｔｃ＝７４６Ｋ，最大磁能积（ＢＨ）ｍａｘ＝１９９ｋＪｍ－３的Ｓｍ２Ｆｅ１７Ｎｙ粉末与粘结体．
The preparation process of Rare earth Compound Sm 2Fe 17 N y such as arc melting,N 2 absorbing and ball milling have been fully and accurately studied.The super Sm 2Fe 17 N 3 powder with Curie temperature has been obtained.
