Abstract：

To　study　the　hot　deformation　behavior　of　Al-Mg-Er　alloy,　hot　compression　tests　were　conducted　on　a　Gleeble-1500D　thermal　simulator　at　the　temperature　range　of　200-500oC　with　the　strain　rates　from　0.001　to　10s-1.　With　the　increase　in　the　deformation　temperature　and　the　decrease　in　strain　rates,　the　flow　stress　of　the　Al-Mg-Er　alloy　decreased.　Processing　maps　were　constructed　to　study　on　hot　workability　characteristics.　The　results　showed　that　the　flow　stress　curves　exhibited　the　typical　dynamic　recrystallization　characteristics　and　the　stress　decreased　with　the　increase　of　deformation　temperature　and　the　decrease　of　strain　rate.　Moreover,　the　processing　maps　were　established　on　the　basis　of　dynamic　material　model　and　Prasad’s　instability　criterion.　©　2018　Trans　Tech　Publications,　Switzerland.
