The microstructure, deformation as well as frac- ture behaviour have been observed by SEM and TEM. It has been found that the mechanism of deformation and fracture for different heat-treated alloys with the same chemical composition is quite different. The cause led to the drop of ductili- ty, toughness as well as anisotropy in peak-aged alloys have been analysed. Finally, possible methods to improve the ductility and toughness of the alloys have been discussed. %K Al-Li based alloy %K microstructure %K mechanical properties
