"Low cycle fatigue properties of lamellar TiAl with 8 at.% Nb were studied at four temperatures: room temperature, 700, 750 and 800 \u00B0C. Up to 750 \u00B0C, stable cyclic behaviour is observed while cyclic softening is characteristic for 800\u00B0C. The strength of the alloy is still high even at 800 \u00B0C. The TEM observation did not reveal any substantial changes in the microstructure due to the cycling at RT. At 750 \u00B0C, the lamellar structure was in some places destroyed by cyclic plastic straining and pure -phase islands with high density of dislocation debris were formed. At 800 \u00B0C, the domains without lamellar structure cover about 10% of volume and are almost dislocation free. The destruction of lamellar microstructure and possible annealing of dislocation debris is the reason for marked cyclic softening at 800 \u00B0C." .
