Abstract Scope Mg alloys need to be thermomechanically treated at elevated temperatures due to the limited formability at room temperature. Electropulsing treatment (EPT) is a new method of heat treatment that utilizes Joule heating directly through electric current to a metal specimen. The process has various advantages, such as rapid heating and energy efficiency, in comparison to the conventional heating method. The authors’ recent study suggested the anisotropic nature of EPT, namely electropulsing anisotropy. Specifically, AZ31 Mg alloy exhibits distinct kinetics of microstructural evolution depending on the direction of electropulsing. As the following study, this present work further investigates the electropulsing anisotropy excluding the effect of grain boundaries. EPT was applied in three directions using AZ31 Mg plate composed of equiaxed grains, which allow for a detailed study of the sole effect of texture on the anisotropy.
