Analysis by EPMA shows that the peak value of distribution of nitrogen element inside the pure iron with ion RE-nitridation is about 100 μm deeper than that with ion nitridation. Investigations by SAED and HRTEM show that the γ'(Fe_4N) phase exists as the uncomplete 6H type long period structure due to the effect of RE elements. There is a near K-S orientation relationship between a-Fe and γ' phase. The RE elements also exist as intermetallic compound (Ce, La)Fe_7which has approximate orientation relationship with α-Fe as follows: Correspondent: WU Yaqiao, Laboratory of Aiomic Imaging of Solids, Institute of Metal Research, Chinese Academy of Sciences, Shenyang 110015 Key words:  pure iron      RE element      nitrogen element      ion-RE-nitridation      structure of surface layer      Received:  18 July 1996      Service E-mail this article Add to citation manager E-mail Alert RSS （） Articles by authors URL:  https://www.ams.org.cn/EN/     OR     https://www.ams.org.cn/EN/Y1996/V32/I7/705 1余景生,余宗森．见:余宗森主编,稀土在钢铁中的应用,北京:冶金工业出版社,1987:12 吕振家,吕其岗．见:余宗森主编．稀土在钢铁中的应用,北京:冶金工业出版社,1987:3603 孙东升,李凤照,张保荣．金属热处理学报,1992,9:464 GerardinD．MenMemSciRev,Metall．1977;74:4575 郑经,王育烽,沈甫法,余德刚,毛树楷．金属学报,1985;21:A2336 顾文桂,周天健．金属热处理学报,1990;11(4):437MichelH,CzerwiecT,GantoisM,AblitzerD,RicardA．SurfCoatTechnol,1995;72:1038HaywoodBC．HeatTreating．1991;3:119LIZhonghou,SUYunan,LIUXiaoping,XUZhong．ActaMetallSin(EngLett),1995,8:14510 BellT,KinaliM,MunstermannG．HeatTreatMet．1987;2:4711吴亚桥,杨林,赵忠俭,高丽峰,徐永波,吕振家．金属学报,1996;32:594H [1] ZHANG Ke; NIU Yan; WU Weitao.
