Light band, fine cell, cell-dendrite structure and disordered dendrite are found in the surface layer, meanwhile, the causes for their formation have been analyzed. The typical cell-to-dendrite transition is observed at the center of laser melt pool, and a detailed investigation on the transition conditions shows that the critical transition velocity determined by experiment agrees well with the prediction of recent BJT model.Correspondent: PAN Qingyue, Lab.403, Northwestern Polylechnical University, Xi'an 710072 Key words:  laser surface remelting and solidification      stainless steel      cell-to-dendrite transition      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/I7/718 1ZimmermannM,CarrardM,KurzW．ActaMetall,1989;37:33052GillSC,ZimmermannM,KurzW．ActaMetallMater,1992;40:28953GillSC,KurzW．ActaMetallMater,1993;41:35634 GremaudM,CarrardM,KurzW．ActaMetallMaler,1990;38:25875GremaudM,CarrardM,KurzW．ActaMetallMater,1991;39:14316KurzW,GilgienP．MaterSciEng,1994;A178:1717SarkissianA,KarmaA．MaterSciEng,1994;A178:1538ZimmermannM,KarmaA,CarrardM．PhyRevB,1990;42:8339陆世英,张德康．不锈钢应力腐蚀破裂,北京:科学出版社,197710 褚武扬．氢损伤和滞后断裂,北京:冶金工业出版社,198811 MudaliUK,DayalRK．JMaterEngPerform,1992;1:34112MudaliUK,DayalRK,GnamamoorthyJB,KanetkarSM,OgaleSB．MaterTransJIM,1991;33:84513 黄卫东,毛志英,周尧和．金属学报,1986;22:B24014 KurzW,FisherDJ．ActaMetall．1981;29:1115BurdenMH,HuntJD．JCrystGrowth,1974;22:21916SomboonsukK,MasonJT,TrivcdiR．MetallTrans,1984;15A:96717HoadleyAFA,RappazM,ZimmermannM．MetallTrans,1991;22B:10118BilliaB,JamgotchianH,TrivediR．JCrystGrowth,1990;106:410 [1] WANG Bin, NIU Mengchao, WANG Wei, JIANG Tao, LUAN Junhua, YANG Ke.
