Abstract：

Hot　deformation　behavior　of　the　3003　Al　alloy　was　investigated　by　conducting　hot　compression　tests　at　various　temperatures　(300-500　°C)　and　strain　rates　(0.0l-10.0　s　-1　).　A　constitutive　equation　was　established　to　describe　the　flow　behavior.　The　apparent　activation　energy　of　the　3003　Al　alloy　was　determined　to　be　174.62　kJ·mol　-1,　which　is　higher　than　that　for　self-diffusion　in　pure　Al　(165　kJ·mol　-1).　Processing　maps　at　a　strain　of　0.6　for　hot　working　were　developed　on　a　dynamic　materials　model.　The　maps　exhibit　a　flow　instability　domain　at　about　300-380　°C　and　1.0-10.0　s　-1.　Dynamic　recrystallization　occurs　extensively　in　the　temperature　range　of　450-500　°C　and　at　the　strain　rate　of　10.0　s　-1.　The　optimum　parameters　of　hot　working　for　the　3003　Al　alloy　are　confined　at　500　°C　and　10.0　s　-1　with　the　highest　efficiency　(37%).　©　KIM　and　Springer.
