The results show that all the initial bainites formed in different alloys at different temperatures are with three-dimensional ledges on the broad faces and/ or at the growth edges of α1 plates but without internal stacking faults, which proves that ledges exist generally on bainites in Cu-Zn-Al alloys and that the growth of bainites is governed by a diffusion-controlled ledgewise mechanism. Key words:  Cu-Zn-Al alloy      bainite      ledge      Received:  18 September 1995      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/Y1995/V31/I9/381 lKajiwaraS．TransJIM,1976;17:4352FlewittPEJ,TownerJM．ActaMetall,1966;14:10133HornbogenE,WarlimontH．ActaMetall,1967;22:9434韩明,陈复民,陈金铭,陈玉如,刘文西．金属学报,1990;26:A815杨延清,刘东慧,康沫狂,孙原．金属学报,1992:28:A956ChattopadhyayK,AaronsonHI．ActaMetall,1986;34:6957WuMH,PerkinsJ,WaymanCM．ActoMetall,1989;37:18218方鸿生,李春明,王家军．金属学报,1993;29:A3839李春明,方鸿生．科学通报,1994;39:98010李春明,方鸿生．自然科学进展,1994;4:75111孟祥康,康沫狂,杨延清,刘东慧,洪建明,刘治国．自然科学进展,1993:3:21912孟祥康,康沫狂,赵小宁,洪建明．电子显微学报,1993:6:488b [1] ZHAO Yafeng, LIU Sujie, CHEN Yun, MA Hui, MA Guangcai, GUO Yi.
