Anisotropy or brittleness poses an obstacle to the rolling of wide magnesium alloy foils, particularly those with a thickness of 1.0 mm. To address this problem, a special electroplastic rolling (EPR) process was developed to provide a better method than traditional isothermal heat treatment. Actual measured results showed that the pulse current with high energy could rapidly adjust high brittleness and severe anisotropy. This condition was helpful in the plasticity and rollability of wide magnesium alloy foils during continuous EPR process. Finally, a 0.13 mm-thick magnesium alloy foil was successfully rolled through continuous EPR processes without any intermediate annealing or reheating in the furnace. Evidently, the developed method contributed to the best matching conditions between the pulse current and deformation parameters along different directions. Therefore, EPR is a promising technology for changing the anisotropy or brittleness of wide magnesium alloy foils online. [ABSTRACT FROM AUTHOR]
