Fig. 19: Degradation rate factor of the tensile mechanical properties of pre-corroded AA2024-T3 specimens for different exposure times to EXCO solution in different artificial ageing conditions.

From: Corrosion of aluminium alloy AA2024-Τ3 specimens subjected to different artificial ageing heat treatments

Fig. 19

The average values of the conventional yield stress Rp0.2% shown in (a) and elongation at fracture Af shown in figure (b) as calculated in Fig. 18 are presented in logarithmic scale. The standard deviation of the values was also calculated and included in the figure as error bars. The equation of the fitting curve is also included in the figure.
