The microstructure, deformation as well as frac-ture behaviour have been observed by SEM and TEM. It has been found that themechanism of deformation and fracture for different heat-treated alloys with thesame 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 beendiscussed.
