Characterization of trapped hydrogen in exfoliation corroded aluminium alloy 2024

Stress corrosion and corrosion fatigue represent major threats to the structural integrity of aircraft structures and have been extensively investigated [1–3]. Among others, Pantelakis et al. [4] observed dramatic degradation of toughness and ductility of Al-Li alloys 2091 and 8090, as well as conventional 2024 alloy in several types of accelerated corrosion tests. Based on a comparison of mechanica
