Cyclic response and fatigue life of TiAl alloys at high temperatures

Original language description

Fatigue properties of the new generation of TiAl alloys with 8at.% of Nb were studied and compared with those reported in the literature for previous generation with 2at.% of Nb. The high Nb content improves substantially the fatigue life time in the Basquin representation. Nevertheless, the fracture behaviour is still rather brittle even at 750°C. TEM study of the material after the fatigue testing was performed. The dislocation activity is concentrated in the gamma phase. The properties and behaviourof individual dislocations seem to be similar as those observed in single gamma phase TiAl alloys.
