%X The effects of electric field on recovery, recrystallization and texture of cold rolled Al--Mn--Mg alloy sheets were investigated by TEM and X ray analysis (ODF). The results show that when the intensity of electric field changes between 2 and 3 kV/cm, the electric field has no obvious effect on recrystallized progress of the cold--rolled Al--Mn--Mg alloys sheets. When the intensity of electric field was 4 kV/cm, it retards the recovery and recrystallization significantly. So It is believed that there is a threshold value (3 $\sim$4 kV/cm ) which decides the effect of electric field on recrystallization. The effects results from that the electric field retards the mobility of dislocation. Furthermore, the electric field annealing reinforce the cube texture of this sheet.
