      • Abstract
    • Different solid solution and aging treatments were performed with 7075/6009 aluminum alloy laminated composite plate to obtain the optimal heat treatment process, and the mechanical properties and tensile fracture of the composite plate after heat treatment were analyzed. The results show that the optimal heat treatment process of the composite plate was solid solution at 485 ℃ for 30 min followed by water quenching and aging at 175 ℃ for 8 h followed by cooling in furnace. The tensile strength, yield strength and elongation of the composite plate were 404 MPa, 364 MPa and 15.3 %, respectively. A lot of dimples was found on the tensile fracture of outer layer 6009 aluminum alloy and the innerlayer and outerlayer alloys had a good metallurgical bonding.
