Flow　stress　characteristic　of　1235　aluminum　alloy　treated　by　different　purification　methods　was　studied　by　dynamic　thermo-simulation　test.　The　effects　of　oxide　inclusions　on　steady　flow　stress,　peak　stress,　and　true　strain　corresponding　to　peak　stress　were　also　examined　in　this　study.　The　results　showed　that　there　is　a　steady　flow　feature　in　1235　aluminum　alloy　during　hot　compression　deformation.　1235　aluminum　alloy　with　lower　inclusion　content　shows　higher　strength,　therefore,　the　plasticity　and　toughness　are　better　and　improve　the　hot-working　character　of　the　alloy.　Therefore,　reducing　inclusion　content　is　effective　for　improving　the　hot　deformation　character　of　aluminum　foil　(1235　aluminum　alloy).
