EFFECTS OF PREBENDING RADII ON MICROSTRUCTURE AND FATIGUE PERFORMANCE OF AL-ZN-MG-CU ALUMINUM ALLOY AFTER CREEP AGE FORMING

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 fatigue performance of the alloy after creep age forming were obtained.In addition, the microstructure and fatigue fracture of the alloy were observed sony c by transmiss
