The effect of solution treatment temperature on mechanical properties and fracture behavior of 7N01/7050 aluminum alloy multilayer plate are investigated in this paper. With the increase in solution treatment temperature, the size of the second phase decreases, while the size of the sub-grains increases. Moreover, the tensile strength and impact toughness of the multilayer plate first rise and then decrease as the solution temperature increases. With solution treatment at high temperature, overheat structures are founded in 7050 layer, resulting in the deterioration of mechanical properties. An improved dissolution of the residual phase, a lower recrystallized grains fraction and smaller sub-grains can be acquired by proper solution treatment in both 7050 and 7N01 layers. This leads to a higher tensile and impact property of 7N01/7050 aluminum alloy multilayer plate.
