Microstructure　features　and　dynamic　softening　behavior　of　aluminum　sheet　for　easy-open　can　during　hot　deformation　were　analyzed　by　hot　deformation　simulator　and　TEM　(transmission　electron　microscope).　The　results　show　that　dynamic　recovery　occurs　at　a　low　temperature　with　a　strain　rate　of　0.1s　-1,　and　dynamic　re-crystallization　appears　obviously　with　temperature　higher　than　723K.　Dynamic　re-crystallization　can　be　observed　in　the　sheet　with　a　low　strain　rate　at　673K,　when　strain　rate　is　higher　than　0.1s-1,　with　increasing　in　strain　rate,　softening　behavior　is　characterized　by　the　combination　of　dynamic　recovery　and　dynamic　re-crystallization.　However,　it　is　characterized　by　geometry　dynamic　re-crystallization　with　strain　rate　more　than　5.0s-1.
