Abstract

Deformation scheme and pre-heat treatment of Al-5.2%Zn-2.3%Mg aluminum alloy is chosen, homogenizing annealing at 415℃ for 1h, cooling to 200℃ in furnace at a cooling rate of less than 30℃/ h and then cooling to room temperature to make Al-5.2%Zn-2.3%Mg aluminum alloy annealed fully. Heat treatment tests of Al-5.2%Zn-2.3%Mg aluminum alloy mainly consisting of rolling and aging were conducted, and the optimum peak aging mechanism is 120℃/20 h. Through comparison of microstructure and mechanical properties with different deformation and aging mechanism, effect of deformation rates and aging mechanism on properties of Al-5.2%Zn-2.3%Mg aluminum alloy was analyzed, and optimum double-peak aging mechanism is 110℃/7h+170℃/16 h. Orthogonal experiments were carried out to analyze mechanical and electrical properties of tested materials before and after deformation, and effect of aging mechanism on Al-5.2%Zn-2.3%Mg Al alloy was analyzed, and the optimum regression aging mechanism is 120℃/20 h+170℃/40 min+120℃/20 h.
