This study has shown that the fracture of titanium alloy 6246 at high temperature is very sensitive to the loading path. In addition, it is demonstrated that the concept of the critical void size, provided by Rice and Tracey`s approach, is only applicable to high triaxialities ({chi} > 0.9). Under low triaxiality ({chi} {le} 0.9) the plastic flow instigates the damage process, favoring shearing instability in prior {beta} grain.
