Effect　of　oxide　inclusion　on　dynamic　recrystallization　behavior　of　1235　aluminum　alloy　were　investigated　by　hot　compression　deformation　tests　on　a　Gleeble-1500　simulator　and　a　dynamic　recrystallization　kinetics　model　was　established.　Results　show　that　dynamic　recrystallization　occurred　in　1235　aluminum　alloy　treated　by　different　purification　processes　during　hot　deformation.　The　predicted　results　of　dynamicaly　recrystallized　volume　fraction　by　the　model　agrees　well　with　the　measured　ones.　At　the　same　condition　of　deformation,　the　process　of　dynamic　recrystallization　occurs　more　slowly　in　the　alloy　with　less　impurities.　Tiny　inclusions　inhibite　the　growth　of　recrystallized　grains.　As　a　result,　the　recrystallization　grains　are　smaller.
