Fig. 21 Pitting potentials as a function of heat-treatment time for grain matrix and solute-depleted zone associated with grain boundary in AI-4 wt. % Cu alloy. The region of ICC (and also IGSCC) susceptibility is indicated. (After Ref. [80].)...

The phase at the aUoy s grain boundary controls ahoy reactivity or enhances reactivity of the associated solute depleted zone (SDZ) [45]. The aerospace ahoy Al-Zn-Mg (7000) series exhibits SCC susceptibility when ahoyed with Cu. Cu segregation and grain... [Pg.18]

Fig. 1.16 Electron microscopy images and EDX profiles around grain boundaries of the Al-Cu alloy aged at 433 K for 7.2 ks. (a) under-aged, (b) 90 k (peak-aged), and (c) 1728 ks (over-aged). The average widths of precipitate free zone (PFZ) and solute depletion zone (SDZ) are indicated by arrow [46].
