The as-RS microstructures of the alloys are quite different to the as-cast one. First, the grains of the RS alloys are finer. Secondly, the Ti_3Al-base alloys with D0_(19) structure in normal condition have transformed fully into ordering orthogonal martensite α″in the RS microstructure. And then, α″,α″+β0, or β0 has been observed sequentially in the RS Ti_3Al-Nb alloys according to the addition of Nb,the strong β-isomorphous stabilizer of Ti,and the APBs in β0 in the RS Ti_3Al-Nb alloy are finer.CUI Yuyou, Institute of Metal research, Chinese Academy of Sciences,Shenyang,110015 Key words:  Ti_3Al alloy      rapid solidification      orthogonal martensite      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/Y1994/V30/I12/545 1NaraS,ThomasM,KhanT．MaterSciTechnol,1992;8:2912FroesFH,SuryanarayanaC,EliezerD．ISIJInt,1991;31:12253JonesH．RapidSolidificationofMetalsandAlloys．MonographNo．8,London:TheInstituteofMetallurgists,19824BhashaianTA．IntJRapidSolidi,1992;7:1275SuryanarayanaC,FroesFH,RoweRG．IntMaterRev,1991;36:856卢斌．中国科学院金属研究所硕士学位论文,19937EA等著,陈石卿译．钛合金金相学．北京:国防工业出版社,1986:788StrychorR,WilliamsJC,SoffaWA．MetallTrans,1988;19A:2259SutlliffJA,RoweRG．In:GiessenBC,PolkDE,TaubAIeds．,RapidlySolidifiedAlloysandTheirMechanicalandMagneticProperties,Pittsburgh,PA:MRS,1986:37110JacrsonAG,TealKR,EylonB,FroesFH,SavageSG．In:GiessenBC,PolkDE,TaubAIeds．,RapdilySolidifiedAlloysandTheirMechanicalandMagneticProperties,Pittsburgh,PA:MRS,1986:36511KaufmanMJ．In:LacombeP,TrucotR,BerangerGeds．,Proc6thWorldConfonTitanium,LesUlisCedex,LesEditions,dePhysiyne,France,1990:98512MorniraliJP,GantoisM．MemSciRevMetall,1973;70(11):83113王金友,葛志明,周彦邦．航空用钛合金．上海:上海科学技术出版社,1985:13714PetersJA,BassiC．ScrMetallMater,1990;24:915, [1] LIANG Chen, WANG Xiaojuan, WANG Haipeng.
