%X The microstructive and compressive properties of Ti50Al48,Mn2 and Ti50Al48Cr2 alloys are studied in this paper. Existence of x-x y transformation in TiAl alloys is confirmed by metallographic examination, the transformation temperatures of Ti5()Al48 Mn2 and Ti50Al48Cr2 are 1375 and 1373 C , respectively. After treating within x y phase field, the microstructure of alloys consists of lamellar zones (I) and bulk rp. The volume ratio of L /rp increases with increasing solution treatment temperature. The third alloying elements of Mn and Cr distribute perferentially over x phase at solution treatment temperatures and result in that x2 and r lamellae become thicker. The yield strength of Ti50Al48Mn2 and Ti50Al48Cr2 alloys decreases and the compressibility increases with increasing rp volume fraction.
