摘　　要：讨论了再结晶退火工艺对0.0045/0.005 mm超薄铝箔坯料纵、横向拉伸力学性能的影响,同时分析了经370℃×6 h退火后铝箔坯料纵、横向拉伸的断裂方式。箔坯纵、横性能及断裂方式的差异,将导致铝箔针孔增加,因此,在加工率及再结晶退火温度一定的前提下,应尽可能地延长保温时间,以降低箔坯的纵、横向性能差异,提高坯料加工性能。The effect of recrystallization annealing process on the longitudinal and transverse tensile mechanical properties of 0.0045/0.005mm ultrathin aluminum foil blank is presented,and the longitudinal and transverse tensile fracture mode of aluminum foil blank after 370 ℃ × 6h annealing is analyzed.The differences of longitudinal and transverse properties of foil blank and the fracture mode will lead to pinhole increasing in aluminum foil,so under a certain processing rate and recrystallization annealing temperature,we should try to prolong the temperature holding time,so that the longitudinal and transverse performance differences of aluminum foil can be reduced,and the processing property of blank can be improved.
