The deformation and fractrure feature of the typical specimens have been observed under SEM and TEM. It is found that the mechanical properties correlated closely with the changes of fracture surface and dislocation configuration. With increasing testing temperature the strength decreased and the ductility increased. but with increasing solution temperature the strength increased and the ductility decreased. The cleavage fracture is revealed at room temperature in the three microstructures and the mixed (cleavage and intergranular) fractrue at elevated temperature. Key words:  Ti_3Al based alloy      tensile deformation      cleavage fracture      Received:  18 June 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/I6/286 1LipsittHA,ShechtmanR．MetallTrans,1980;11A:13692YangWJS．JMaterSciLett,1982;1:1993KhataeeA,FlowerHM,WestDRF．JMaterEng,1988;10:374MuraleedharanK,BanerjeeD．MetallTrans,1989;20A:11395ChanKS．MetallTrans,1992;23A:1836ChaveRA,BeeversCJ,BowenP．In:edisBailonJB,DicksonJI,Fatigue'93,1993;2:10077艾素华,关少轩．冯泽民,葛景岩．金属学报,1995;31(4):A183 [1] TIAN Ni, SHI Xu, LIU Wei, LIU Chuncheng, ZHAO Gang, ZUO Liang.
