%X The tensile properties of Ti3Al based alloy undergone 3 different regimes of solutioning treatment have been examined at room and elevated temperatures. 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.
