Modifying the gain orientation is considered a crucial method for enhancing the corrosion resistance of Mg alloys. This study aims to improve the corrosion properties of AZ31 alloy sheet through pre-stretch deformation, specifically compression (6.8%) along the extrusion direction (ED). To eliminate the twin structure, a recrystallization annealing process was performed after the pre-stretch deformation. To investigate the corrosion performance of Mg alloys, we conducted electrochemical and hydrogen evolution tests, which provided insights into the influence of microstructure on the corrosion resistance of Mg alloys. The results indicate that the corrosion resistance was altered by the presence of twin grain boundaries that formed after pre-stretch deformation. Furthermore, the recrystallized texture with//ED orientation exhibited the highest corrosion resistance, underscoring the significant role played by grain orientation. [ABSTRACT FROM AUTHOR]
