Abstract
The effect of the current density on the formation of the structure of the AD33 Al-Mg-Si alloy during deformation by rolling is studied. It is shown that, at a current density of 30 A/mm2, the electroplastic deformation by rolling (EPDR) of the AD33 alloy increases its ultimate strength. A decrease in the deformability of the material with increasing current density to 100 A/mm2 and higher is related to the melting of fusible eutectic, which leads to the appearance of microcracks at the grain and subgrain boundaries.
