Interrelation between the structure and corrosion resistance in 1370 alloy of Al−Mg−Si−Cu−Zn system

The possible ways of decreasing the intercrystalline corrosion susceptibility (ICS) were analyzed and as a result of the performed studies with the use of 1370 sheets and plates some regularities were established: ICS is reduced with the increase of the relation between Mg and Si and the decrease of the near-frontier precipitation free zone width and the precipitation density at the grain boundaries as a result of using the step-by-step ageing conditions.

Keywords: Al−Mg−Si−Cu system, 1370 alloys, structure, intercrystalline corrosion, precipitation-free zone, multistage ageing
