Abstract

The flow behavior of nanostructured Al-6082 alloy material has been investigated in this paper using an upsetting test. Specimens were produced by the equal channel angular pressing (ECAP) technique and test samples were taken from the three perpendicular axes of the produced parts. The true stress–true strain curves were plotted for all specimens in three directions. Computer software and the Ludwik equation were used to analyze the true stress–true strain curves data in order to determine the stress and strain parameters by plotting the fitted curves onto the true stress–true strain curves. The deformed specimens clearly showed anisotropic behavior.
