摘要	Atom probe tomography (APT) has been used to characterize the element segregation at the grain boundary (GB) for a peak-aged Al-Zn-Mg alloy with high stress corrosion cracking (SCC) susceptibility. The results show that Mg segregates along the GB with a peak concentration of 1.38 at.% and width of 3 nm. Zn does not segregate at GB. However, segregation of Zn and H atoms at oxide-containing clusters on GB has been observed. APT atom maps also reveal that Mg2Si is the H trapping site, but MgZn2 is not. (C) 2013 Elsevier Ltd.
