Key Points

  • Assess intergranular corrosion susceptibility in Al-Mg alloys using laser-induced breakdown spectroscopy.
  • Utilized corrosion transfer methods and laser-induced breakdown spectroscopy for analysis in aluminum alloys.
  • Focused on Al-Mg alloys' sensitization during thermal exposure.
  • Identified the relationship between grain boundary β-phase precipitation and corrosion susceptibility.
  • Demonstrated the effectiveness of this method for reliable quantitative analysis of intergranular corrosion.

Abstract

The susceptibility of Al-Mg alloys to sensitization during thermal exposure, leading to intergranular corrosion (IGC) via grain boundary β-phase (Al₃Mg₂) precipitation, poses a significant threat to their structural integrity in...
