Fig. 10: Images of fractured pre-corroded surfaces of AA2024 in T3 condition.

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

Fig. 10

The surfaces of pre-corroded tensile specimens after tension testing are presented in macroscopic scale. The different exposure times to exfoliation corrosion solution are depicted in different images, i.e., the 0.5 h is provided in (a), the 2 h in (b), the 4 h in (c) and the 24 h in (d), respectively. Upper images show the upper (big) flat surfaces of tensile specimens, and the bottom images show the small side-surfaces (thickness).
