I would like to make the Al5083 micro structure homogeneous before deforming. In which temperature should it be annealed?
Thanks.
Dear Dr. Amir Torabi,
on Al 5083 alloy, a homogeneous ultrafine grained microstructure of an average size of 300 nm with well defined grain boundaries could be achieved with an effective rolling strain of only 2.3 followed by short annealing at 300°C for 6 min.

The annealing behavior of a modified 5083 aluminum alloy was studied in the temperature range of 125–375°C with different holding times. The results shown that the annealing temperature was more sensitive to the mechanical and corrosion resistance properties compared with the annealing holding time. The mechanical and corrosion resistance properties depend on annealing treatment due to different dislocation configuration in the matrix and the second phase interface, annealing temperature and time have been optimized for both of those properties improvement.

In another paper the commercial 5083 (H112 condition) Al alloy plates (Al-4.56%Mg-0.61%Mn) with 6.2 mm in thickness was firstly annealed at 540 °C for 2 h to fully remove defects, and after cold rolled with reduction in pass, finally, the fine-grained 5083 Al alloy was annealed at 150−300° C for 30 min..

Dear Amir,
yes, as the colleagues above state, normally solution heat-treatments for Al alloys consist in 30 to 60 min at temperatures around 450 to 550ºC, as we say in:
