Abstract: The correlation between the diverse fracture modes and the microstructural variation with recrystallization in the Al-Li alloys under heat treatment was observed by means of triplanar optical and scanning electron microscopy.The growth,propagation and feature of their frac- tures were described from the viewpoint of microstructure,energy and geometry.

Key words: Al-Li alloy, fracture, recrystallization, aging
