Title: Mechanical and electrical properties of artificially aged aluminium alloy AA 2024

Abstract: This study investigated the GP(Cu,Mg) regions formed following the artificial ageing of aluminium alloy and the effect of the Al2CuMg phases on the mechanical and electrical properties. First, AA 2024 aluminium alloy samples were maintained in a conventional furnace at 530 °C for 20 min and then subjected to quenching in order to homogenise their microstructures. Then, the samples were subjected to the artificial ageing method for various periods of time in an annealing furnace at 190 °C. Following the artificial ageing of the samples, their internal structure characterization, micro-hardness, mechanical and electrical properties (dielectric) were investigated. Experimental results are discussed compared to literature data.
