论文摘要
2024 aluminum alloy and 7075 aluminum alloy are often used in daily life with excellent mechanical properties,but they are often welded together to withstand fatigue loads,so it is necessary to stir the friction welded joint of 2024-7075 dissimilar aluminum alloy.A detailed study was conducted at the weak location.In this paper,the weak position of the welded joint is analyzed based on the residual stress,and the relevant theoretical model is established to predict the fatigue life based on the residual stress.
