Determination of Loss in Mechanical Properties of 2024 Aluminum Alloys in Different Heat-Treated-State after Corrosion
Abstract :
In this study, the solution treatment of all 2024 Al-alloys was conducted at 510°C for 2,5 hour. Then, the solution heat-treated 2024 Al-alloys were subjected to the various heat treatments which are W, T4, T6 (100oC-10h), T6 (190oC-10h) and O temper conditions. The microstructure of the alloys were examined by optical and scanning electron microscopy (SEM). Static immersion corrosion tests for the tensile samples were carried out in a 3.5 wt. % NaCl solution for 2 months, open to air, at room temperature. The tensile tests of the specimens were carried out before and after corrosion. The results obtained were compared and the losses occurring in the strength and elongation after corrosion were determined. The minimum loss was observed in T4 heat treatment while the maximum loss was occurred in W heat treatment.
