摘要: Abstract 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 used to investigate changes mechanical properties while TEM and XRD observations were utilized in order characterize microstructural evolution during natural aging. Results show that Si-enriched precipitates appear coarsen rapidly first few days TCPed which causes consecutive increase decrease microhardness, respectively. Similarly, other alloying elements such as Cu Fe lead formation coarse alloy. Moderated rate recovery is also observed SPD results progression cell microstructure.
