Many details in nanometer scale were revealed on the fracture surfaces by STM, such as nanometer scale steps, dimples and vacancies. The study of the details on the fracture surfaces will be helpful to the study of the mechanism of fracture. Key words:  Ti3Al intermetalic alloy      cleavage fracture      nanometer scale      STM      Received:  18 May 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/I5/191 1Masuda-JindoK,TewaryVK,ThomsonR．MaterSciEng,1991;A146:2732张跃,王燕斌,褚武扬,肖纪美.科学通报,1994;39:1173ZhangY,WangYB,ChuWY,HsiaoJM．JVacSciTechnol,1994;12B(4)4BinningG,RohreH,GerberC．SurfSci,1983;137:L3795HallmarkVM,ChiangS,RaboltJF．,SwalenJD,WilsonRJ．PhysRevLett,1987;59:28796 SamsavarA,HirschornE S,MillerT．PhysRevLett,1990;65:16077Gomez-RodriguezJM,AsenjoA,SalvarezzaRC,BaroAM．Ultramicroscopy,1992;42:13218SastrySML,LipsittHA．In:KimuroH,Izumi,Oeds．,Titanium'80,Vol．II,Proc4thIntConfonTitaninum,Warrendale,PA:TMS-AIME,1980:12319LipsittHA,ShechtmanD,SchafrikRE．MelallTrans,1980:11A:136910WangXS,GoldbergJL,BarteltNC．Phys Rev Lett,1990;65:243011KaiserWJ,JaklcvicRC．SurfSci,1987;182:L22712OcalC,VazquezdePargaAL,JMicroscopy,1988;152:69713ThibaudauF,CoustyJ．Ultramicroscopy,1992;42:51114BesenbacherF,JensenF．JVacSciTechnol,1991:9B:87415NiehusH,KohlerUK．JMicroscopy,1988;152:73516SalmeronM,OgeltreeDF,OcalC．JVacSciTechnol,1991;98:134717WhitmanLJ,StroscioJA,DragosetRA,CelottaRJ．Science,1991;251:120618ChenCJ．PhysRevLett,1990;65:448 [1] SUN Baode, WANG Jun, KANG Maodong, WANG Donghong, DONG Anping, WANG Fei, GAO Haiyan, WANG Guoxiang, DU Dafan.
