This paper presents results of monotonous tensile tests of 0.16” thick samples made of non-clad plates of aluminium alloy for aircraft purposes 2024-T3. Tests were performed for samples cut out from a sheet plate in two different directions: in the parallel and perpendicular direction to sheet plate rolling direction, for eight different temperature values from the range 25°C – 200°C. The tests were performed using the hydraulic-drive testing machine INSTRON 8502 equipped with thermal chamber. The analysis of results included changes of basic strength-related parameters depending on temperature. It was also observed that the intensity of Portevin-Le Châtelier [PLC) effect depends on the temperature.
