“…On the other hand, L-T orientation presents a "barrier effect" at grain boundaries, promoting a slight decrease in FCGR. This decrease in FCGR can be due to the clustering of second phase particles in the rolling direction, raising the proportion of intergranular failures in T-L oriented specimens, thus reducing fracture toughness [26], [27]. The saline environment has amplified the FCGR in the AA7050-T7451 alloy and had a minor effect on the AA2050-T84 alloy (see Figure 3b).…”
