Abstract

In this study retrogression and aging treatment have been applied to the samples of an aluminum alloy AA 7075-T6. The retrogression treatment has been performed with different temperatures and times and then aging treatment has been applied at 130 degrees C for 12 h. By determining the effects of the retrogression treatment temperatures and times on the samples, the microstructral and also mechanical changes in AA 7075-T6 alloy have been examined. All microstructures have been investigated by Scanning Electron Microscopy (SEM). Additionally, the mechanical properties have been determined by the notched impact test and the tensile test.
