“…Other investigations using 3.5% NaCl solution with additives such as hydrogen peroxide [7,8] and even 3 M NaCl electrolyte solutions with an applied voltage of 0.63 V [5,6] show pitting corrosion as well as intergranular corrosion, exhibiting pit depths in the range 200– 400
[8], respectively, 400– 600
[5]. Since corrosion pits generally lead to an increasing local stress concentration [5,6,11–13], they are the source of crack initiation [14] and hence the reduction of the functional fatigue life time of EN AW-2024-T3 [7,8,15]. But not only the fatigue life time reduces in the presence of local corrosion, but also the yield strength and ductility decreases [2,4,9,11,16–18].…”
