Abstract：At present the study of relation between microstructure ,texture and performanceof CC 5083 aluminium alloy after cold tolling and recrystallization processes is still finitude. So that the use of the CC 5083 aluminium alloy be influenced. Be cased into electrical furnace, hot up with unlimited speed followed the furnace hot up to different temperature and annealed 2h respectively, and be casedinto salt-beth furnace, hot up quickly to different temperature and annealed30min respectively for CC 5083 and CC 5182 aluminum alloy after cold roling with 91.5% reduction. The microstructure be watched use metallographic microscope, the texture be inspected by XRD. The start temperature of recrystallization and grain grow up temperature within annealing in the electric furnace of CC 5083aluminum alloy board is 343 ℃, and the shap of grain after grow up with long strip (the innovation point ); The start temperature of recrystallization within annealling in the salt bath furnace of CC 5083 is 343 ℃. The start temperatureand end temperature of recrystallization within annealling of CC 5083 and CC 5182 aluminum alloy is 371 ℃. The grain grow up outstanding of cold rooled CC 5152 aluminum alloy after annealed with 454 ℃ in the electric furnace and salt bath furnace. The start temperature of grain grow up of CC 5083 alluminum alloy annealed in the electric furnace and salt bath furnace respectively is higherthan the start temperature of grain grow up of CC 5182 alluminum alloy annealed in the electric furnace and salt bath furnace respectively. The strat temperature of recrystallization grain grow up is higher than which annealled with other three manner annealing process. The recrystallization temperature of CC 5182 annealed in the salt bath furnace is higher than which annealed in the electric furnace. The recrystallization temperature of the surface layer of CC 5083 and CC 5182 aluminum alloy is higher than the inner layer (the innovation point). Thereis a difference each other of the structure and the texture of the four manner annealing aluminum alloy (the innovation point). There is a little difference at the recrystallization processes course reflectived by the observe results of structure transform and by the examination results of texture transmission.
