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℃. TEM study of the material after the fatigue testing was performed. The dislocation activity is concentrated in the γ phase. The properties and behaviour of individual dislocations seem to be similar as those observed in single γ-phase TiAl alloys.
