%X Low cycle fatigue property, cyclic hardening and softening of 8090 Al-Li alloys at various aging conditions were studied. The results showed that cyclic response stress in the same aging condition increased with increasing strain amplitude, and aging condition had a little influence on cyclic deformation at low strain amplitude but the influence increased with raising strain amplitude. The characteristics of low cyclic fatigue and cyclic hardening and softening of the alloy were closely related to dislocation morphology, size of precipitate, PFZs along grain boundaries and fracture appearance.
