, China)Abstract:The creep age forming effects of 2524 aluminum alloy at different stresses and aging times were investigated through tensile performance, Vickers hardness and TEM. The results show that the aging time and stress have great effect on not only creep behavior but also microstructure of 2524 aluminum alloy. And the creep behavior will become stronger with heavier stress and longer time......
