In　this　paper,　an　Al-Zn-Mg-Cu　alloy　with　a　small　amount　of　Er　and　Zr　added　was　used　as　the　research　object.　The　homogenization　annealing　was　carried　out,　and　the　7N01　aluminum　alloy　was　used　at　300　°C,　350　°C,　400　°C,　450　°C　and　0.1　s-1,　1　s-1,　10　s-1　deformation　conditions　by　Gleeble-3500　thermal　simulator.　Optical　Microscopy　(OM),　Scanning　Electron　Microscopy　(SEM),　Electron　Backscatter　Diffraction　(EBSD)　and　Transmission　Electron　Microscopy　(TEM)　were　used　for　microstructure　analysis.　The　results　show　that　the　stress-strain　curve　of　with　Er　7N01　aluminum　alloy　can　be　divided　into　micro-strain　stage,　uniform　deformation　stage　and　steady-state　flow　stage　during　the　thermal　compression　process.　The　flow　stress　of　7N01　aluminum　alloy　achieved　peaks　at　the　initial　stage　of　strain,　and　then　increased　with　the　increase　of　strain　rate　and　the　decrease　of　deformation　temperature.　With　the　increase　of　deformation　temperature　and　the　decrease　of　deformation　rate,　the　recrystallization　process　was　significantly　increased.　©　2020　Trans　Tech　Publications　Ltd,　Switzerland.
