چکیده: Superplasticity of AA2024 aluminium alloy processed by multiple compressions in a channel die was investigated by impression testing in the temperature range of 613-703 K. The values of strain rate sensitivity parameter of 0.49-0.56 and activation energy of 73 kJ/mol were obtained by impression creep technique. Based on the obtained results, it can be said that, the processed material exhibit superplastic deformation with the possible creep mechanism of grain boundary sliding. The studied material deformed superplastically in the strain rate range of 10-3-10-2 s-1 which is greater than ranges in which superplastic deformation usually occurs.
