Whether or not the maximum B2 order degree got, the total regularity of the FIM image is so poor that it is even difficult to know the B2 order degree qualitatively. However, the local evaporation characters of the〈100〉pole contain the information of B2 ordering. By successive examination, it is discovered that the evolution of B2 ordering is not homogeneous in nano－scale. The result got from the〈120〉pole is the similar to that from the〈100〉pole. This consistence confirms once more the conclusion"only the Al atoms contribute to the image while the Fe atoms are invisible" .Correspondent: ZHI Rentao, professor, Deportment of Materials Physics, University of Science and Technology Beijing, Beijing 100083 Key words:  Fe_3Al      FIM      ordering      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/I7/695 1SouthworthHN,RalphB．PhilMag,1970;21:232TauntRJ,SinclairT,RalphB．PhysStatSolA,1973;16:4693KrauseHJ,WittigJE,FrommegerG．ZMetallkd,1987;78:5764WengJ,ZhuFW,XiaoJM．ZMetallkd,1994;85:4325MarcinkowskiMJ,BrownN．JApplPhys,1962;33:5376NewmanRW,HrenJJ．PhilMag,1967;16:2117LinY,ZhuF,XiaoJ．AclaMetallMater,1994;42:2499^ [1] HAN Dong, ZHANG Yanjie, LI Xiaowu.
