Abstract

In this study, the effect of aging at different temperatures and times on the microstructure and mechanical properties of AA7075-T6 alloy was investigated. The samples prepared for the experimental studies were subjected to solution, quenching, and then aging heat treatment at 100 ⁰C and 200 ⁰C for different periods (42-66-90 hours). The microstructure and mechanical properties of the experimental samples were investigated by hardness, compression test and scanning electron microscope (SEM). As a result of the studies, it was determined that the aging heat treatment had a positive effect on the microstructure and mechanical properties of the AA7075 alloy compared to the reference sample. Especially as a result of the heat treatments at 100 ⁰C, higher results were obtained in hardness and compression strength compared to the initial values.
