Al 5xxx alloys (Al 5083 H131 and H116) are of great importance for ships and offshore structural applications for the balance of strength, formability, weldability, and corrosion resistance. In this study, samples of Al 5083 H131 and H116 alloys were aged at 343K for 9, 18, and 30 months. Scanning Transmission Electron Microscopy (STEM) and Energy Dispersive X-ray Spectroscopy (EDS) were used to identify the size and Mg concentration of Mg-rich precipitates formed within the matrix of Al 5083 H131 and H116 alloys. In addition, Small Angle Neutron Scattering (SANS) experiments were performed to obtain the particle size distribution and volume fraction of Mg-rich precipitates. The size of Mg-rich precipitates obtained from STEM images matched well with the SANS results.
