Abstract
The concentration of zinc and magnesium across grain boundaries was measured by means of an electron probe microanalyzer for an Ag-Zn-Mg alloy after different quenching (brine, water, oil, and air) and aging heat treatments (room temperature, 165°, and 200°C). Significant solute segregation was detected in quenched specimens and also in specimens that were aged at room temperature. While no solute enrichment was measured in specimens that were aged at elevated temperatures, solute depletion was observed in a considerable proportion of the examined boundaries. It was concluded that solute segregation to grain boundaries occurred during quenching and was relieved during aging.
