The　annealing　behavior　of　a　modified　5083　aluminum　alloy　was　studied　in　the　temperature　range　of　125-375　degrees　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.　(C)　2009　Elsevier　Ltd.　All　rights　reserved.
