This paper presents results of monotonic tensile and creep tests conducted on typical Al-Cu-Mg alloy (commercial 2024) specimens. Tensile tests carried out at room (20°C) and elevated (100°C, 200°C, 300°C) temperatures made it possible to determine strength properties of the material (Young’s modulus, yield stress, ultimate tensile strength). Creep tests were performed at elevated temperature (100°C, 200°C and 300°C) with a constant force. In order to obtain material creep characteristics, creep-rupture tests were carried out. Then creep tests were conducted with two different strain values: one corresponding to the beginning of the secondary creep and the other corresponding to a certain value of the tertiary creep. After preliminary creep deformation at two various strain levels, specimens were cooled at ambient temperature and then subjected to monotonic tensile tests. The characteristics of the material were obtained for pre-strained specimens at different temperatures. Specimens fracture surfaces obtained as a result of tensile (at elevated and room temperature), creep and combined tests were analyzed.
