چکیده انگلیسی
Natural aging behavior of the aluminum 6061 alloy after a novel Severe Plastic Deformation process called Tube Channel Pressing (TCP) was studied. For this purpose, Vickers microhardness test was used to investigate the changes of mechanical properties while TEM and XRD observations were utilized in order to characterize microstructural evolution during natural aging. Results show that Si-enriched precipitates appear and coarsen rapidly in the first few days of natural aging of TCPed aluminum 6061 alloy which causes consecutive increase and decrease of Vickers microhardness, respectively. Similarly, other alloying elements such as Cu and Fe lead to formation of coarse precipitates during natural aging of TCPed aluminum 6061 alloy. Moderated rate recovery is also observed during natural aging after SPD which results to progression of cell microstructure.
