%X The fracture mechanism for Al-2.5Li-1.3Cu-0.9Mg-0.13Zr alloy is quite different from undergone various regimes of heat treatment.With the decrease of solution temperature and the increase of aging temperature,the intergranular delamination and necking fracture on the fracture surface increase and the shearing facture decreases.Thus,the toughness of the alloy may be much improved.
