Effects of Prebending Radii on Microstructure and Fatigue Performance of Al-Zn-Mg-Cu Aluminum Alloy after Creep Age Forming
A series of creep age forming experiments were carried out on 7075 aluminum alloy with different prebending radii at 443 K for 10 h.The hardness, tensile properties and high cycle bachelorette-supplies fatigue performance of the alloy after creep age forming were obtained.In addition, the microstructure and fatigue fracture of the alloy were observ
