The　stabilization　treatment　of　5E83　alloy　is　investigated　by　optical　microscopy,　transmission　electron　microscopy,　and　electron　backscattered　diffraction　in　this　work.　Through　the　mechanical　properties　and　corrosion　properties　of　the　initial　state　of　5E83　aluminum　alloy　hot-rolling　sheet　and　the　annealed　state　of　240–260　°C/1–24　h,　combined　with　the　microstructure　analysis　of　the　corresponding　state　to　optimize　the　stabilization　process　of　5E83　alloy　hot-rolled　sheet　and　explore　the　changes　in　its　performance　and　microstructure　with　the　annealing　system.　The　results　show　that　the　weight　loss　curve　of　5E83　alloy　hot-rolled　sheet　rapidly　enters　the　sensitive　area　from　the　passivation　zone　at　the　annealing　temperature　of　240　°C.　It　enters　the　insensitive　area　from　the　passivation　zone　with　the　annealing　time　at　the　annealing　temperature　of　250　and　260　°C.　According　to　the　above　experimental　results,　it　is　finally　determined　that　the　annealing　at　260　°C　for　more　than　20　h　is　a　suitable　stabilization　process　for　the　5E83　alloy　hot-rolled　sheet,　and　the　intergranular　corrosion　performance　of　the　alloy　is　good　in　this　state.　©　2019,　Springer　Nature　Singapore　Pte　Ltd.
