Aging Characteristics Of Aluminum-Silver Alloys, Paul Leray Reynolds
Retrospective Theses and Dissertations
The effect of single-step and two-step aging treatments on the tensile properties of an Al-6 wt. % Ag alloy and an Al-14 wt. % Ag alloy has been investigated. Results show that the tensile properties of these alloys were approximately the same whether they were given single or two-step aging treatments. Reversion treatments applied to the fully age-hardened Al-14 % Ag alloy after 15 minutes at various temperatures between 200 and 350 °C showed two maxima in the ultimate tensile strength and the yield strength. It is believed that this result was caused by two transformation processes occurring simultaneously: i.e., …
