Ti_3Al+Si+Nb alloys containing Ti_5Si_3 have the potential in ductility improvements. In this paper, the fracture mechanism of this alloy is under investigation. Three kinds of alloys in the as rolled condition were prepared for determination of KIC values and calculation of J-resistance curves. The results show that the morphology of Ti_5Si_3 has a great influence on the KIC. values of the alloys and crack growth resistance. The fracture mechanism is controlled by Ti_5Si_3 particles.
