Abstract
The strengthening effects of hot/cold rolling and surface mechanical attrition treatment (SMAT) on aluminium alloy were investigated in this paper. Before performing the rolling processes, aluminium sheets were treated using SMAT on both sides for 40 min at room temperature. The parameters for the hot/cold rolling process included a range of operating temperatures (-200°C to 480°C) and percentages of thickness reduction (up to 85%). Then the mechanical properties of rolled samples of different thicknesses were studied. Tensile test results showed that the higher the percentage of reduction in thickness, the higher the strength of the rolled samples that could be obtained. Considering the yield and tensile strength, rolling at room temperature with 80% thickness reduction was the optimum condition for AA2024-T3 in this article, in which the yield and ultimate tensile strength were increased by 54% and 79% respectively. It was also found that the ductility was also enhanced according to the operating temperature.
