摘　　要：连续冷却铸造5083铝合金板较大塑性变形量冷轧后的组织、织构及性能与再结晶处理工艺关系的研究有限。对冷轧压下量约为91.5%的CC5083与CC5182铝合金板分别进行室温入箱式电炉、随炉不限速升温到不同温度退火2 h和分别进行直接入不同温度盐炉退火30 min、出炉水冷至室温后,采用偏光金相显微镜观察组织、采用X射线衍射检测织构,进一步对比研究较大压下量冷轧后退火工艺与再结晶组织和织构关系。结果显示:(1)电炉退火CC5083铝合金板的再结晶开始及晶粒长大温度为343℃,晶粒长大后形状为长条状(创新点);盐炉退火CC5083铝合金板的再结晶开始温度为343℃;二者再结晶完成温度都为371℃。(2)CC5182铝合金板分别在电炉与盐炉454℃以上退火,晶粒开始显著长大;电炉退火与盐炉退火CC5083铝合金板再结晶开始温度分别高于电炉与盐炉退火的CC5182铝合金板,盐炉退火CC5083铝合金板再结晶晶粒长大温度高于另外三种方式退火;CC5182铝合金板盐炉退火再结晶晶粒长大温度高于电炉退火的。CC5083和CC5182铝合金冷轧板表层再结晶及再结晶晶粒长大温度明显高于内层的(创新点)。(3)四种方式退火再结晶晶粒长大温度及相同温度退火时织构转变程度有差异(创新点);退火过程中织构检测结果与金相组织观察结果反映的再结晶进程不很一致。At present the study of relation between microstructure ,texture and performance of 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 re-spectively,and be cased into salt-beth furnace,hot up quickly to different temperature and annealed 30min respectively for CC 5083 and CC 5182 aluminum alloy after cold roling with 91.5% reduction.The microstructure be watched use metallographic mi-croscope,the texture be inspected by XRD.The start temperature of recrystallization and grain grow up temperature within an-nealing in the electric furnace of CC 5083 aluminum 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 temperature and 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 higher than the start temperature of grain grow up of CC 5182 alluminum alloy annealed in the e-lectric 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 fur-nace 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）.There is a difference each other of the structure and the texture of th
