摘　　要：为了改善7×××系某铝合金板材的塑性,试验研究了退火工艺参数对7×××系某铝合金冷轧板材组织和力学性能的影响。研究结果表明,7×××系某铝合金冷轧板材,开始再结晶温度为200℃,终了再结晶温度为360℃;最佳完全退火制度为退火温度380℃~390℃,保温1.0 h;可作为制定工业生产7×××系某。O状态某铝合金板材退火工艺制度的基础。To improve the plasticity of a 7×××aluminum alloy sheet,the annealing process has been investigated for the 7×××aluminum alloy cold rolling sheet in order to make clear how the annealing effects on the structure and mechanical property of the alloy sheet.The investigations show that the recrystallization starts at temperature 200℃ and ends at 360℃ for alloy 7×××cold rolled sheet.The optimum annealing system is 380℃-390℃ with 1 hour holding time.This annealing system has been settled for producing 7×××-O aluminum alloy sheet at industrial production condition.
