Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p>The role of chemistry in affecting dealloying along and across grain boundaries is investigated in nanocrystalline Ag–Au and Cu–Au. The microstructural evolution, through a combination of in situ and ex situ electron microscopy, is correlated with measurements of grain boundary chemistry via a statistical analysis. A critical concentration of segregated Au, 40%, inhibits grain boundary corrosion and strongly influences the microstructural evolution. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgjf85cgp7" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
