Abstract
In this study the mechanical properties and corrosion behavior of both 5083 and 5086 marine aluminum alloys had been studied in the Tigris River at room temperature (23 °C) in two different distances (15 and 30 m away from the beach) at a depth of 1.5 m before and after recovery annealing. After recovery annealing at a temperature of 250 °C for a period of 45min, the corrosion resistance in both alloys had been decreased. This indicates that recovery annealing is not suitable to improve the corrosion resistance of these alloys in Tigris River. The yield, tensile stress and hardness of both alloys were decreased while the elongation increased as a result of recovery annealing. Optical microscopy indicates that these alloys will suffer from localized corrosion
