English Abstract

In the present work the mechanical properties and corrosion behavior of both aluminum magnesium alloy grade 5083 and 5086 were studied in Tigris River at the beach, before and after recrystallization annealing at room temperature (23 0C).

The corrosion resistance of both alloys decrease after these alloys were recrystallization annealed at temperature of 350 0C for 25min for 5083 this increasing was from 2.493 × 10-3 to 51.24 × 10-3and for 5086 it was from 187.7 × 10-6 to 24.41 × 10-3 both alloys will suffer from localized corrosion as a result of recrystallization annealing.

The yield, tensile stress and hardness of both alloys decrease, the tensile stress of 5083 decrease in the percentage of 9.8% , while the yield decrease in the percentage of 15% For 5086 it was 5.071% and 10% respectively while the elongation of both alloys increase in the percentage of 20% .

The hardness of 5083 and 5086 increase in the percentage of 17.6% and 23% respectively.
