Effects of micro-scale corrosion damage features and local microstructure on fatigue crack initiation location

•Corrosion and microstructure characterized a fatigue initiation sites in AA7050.•No independent correlation between individual features and initiation locations.•Strongly suggests a coupled interaction of features governs the initiation behavior. The fatigue resistance of aerospace structures is de...
