The shape, size and distribution of subunits under TEM are the same as those obtained by scanning tunneling microscope. The ledges on subunit were found to be grown up by ledgewise mechanism. The subunits are sympathetically nucleated. Three types of sympathetic nucleation were observed: face-to-face, edge-to-edge and edge-to-face.Correspondent: LI Chunming, (Laboratory of Laser Single Atom Detection, Department of Modern Applied Physics, Tsinghua University, Beijing 100084) Key words:  Cu-Zn-Al alloy      bainite      subunit      sympathetic nucleation      ledgewise growth      Received:  18 January 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/I1/1 1方鸿生,李春明,王家军,杨志刚,薄祥正,邓旭蕊,严隽珏,于洪滨,黄刚．中国科学(A辑),1994;24:8922FangHS,LiCM．MetallMaterTrans,1994;25A:26153李春明,方鸿生．科学通报,1994,39:9804李春明,方鸿生．自然科学进展-国家重点实验室通讯,1994;4:7515AaronsonHI,WellsC．TMS-AIME,1956;206:12166StreetJA,AaronsonHI,SpencerCW．JInstMetals,1959-60;88:3817UnnikrishnanM,MenonESK,BanerjeeS．JMaterSci,1978;13:14018方鸿生,王家军．金属学报,1994;30:A4919FangHS,WangJJ,LiCM,ZhengYK．In:94′TMS FallMeeting,Chicago:ASM&TMS,1994:6010方鸿生,王家军,杨志刚,李春明,邓旭蕊,郑燕康,严隽珏,于洪滨,李志刚,黄刚．自然科学进展-国家重点实验室通讯,1993;3:52511ChattopadhyayK,AaronsonHI．ActaMetall,1986;34:695 [1] ZHAO Yafeng, LIU Sujie, CHEN Yun, MA Hui, MA Guangcai, GUO Yi.
