Abstract

In this study, the synergistic effect of equal-channel angular pressing (ECAP) and aging temperature-time on the mechanical properties of AA6082 has been investigated. The treatments include post-ECAP artificial aging and dynamic aging which was achieved by ECAP processing at 140 °C to 1 pass. It was observed that both routes were effective in enhancing the strength of the alloy. The Vickers microhardness measurements were recorded at three different aging temperatures with varying time intervals. The hardness values of the ECAP-processed alloy to 1 and 2 passes, followed by artificial peak aging was found to be 112.3 and 130 Hv, respectively. Compared to the yield strength of solution-treated alloy, the synergistic effect of ECAP processing to 1 pass and 2 passes followed by artificial aging has resulted in an increase in the yield strength of the alloy by 140 and 183%, respectively. The dynamic aging resulted in an overall increase in the yield strength of the alloy by 177%. The correlation from the modified Johnson-Cook model was close to the observed experimental responses.
