Research on Corrosion Fatigue Crack Propagation Behavior of Welded Joints of A7N01P-T4 Aluminum Alloys

J. Chen, J. Xu, M. Zhao, G. Gou

Abstract: Corrosion fatigue crack propagation behavior of welded joints a of A7N01P-T4 aluminum alloys were investigated. The corrosion fatigue crack propagation rate of base metal is higher than that of the heat-affected zone and the welding seam has a better corrosion fatigue resistance.
