摘要：
In this study, symmetric rolling (SR), unidirectional asymmetric rolling (UASR) and reverse asymmetric rolling (RASR) were conducted in AZ31B alloy, and the corrosion behaviour of AZ31B alloy deformed via these processes mentioned above were studied. The results indicated that samples deformed via the RASR process exhibited a more homogeneous microstructure with refined grains. As a result, samples deformed via the RASR process had the highest open circuit potential (OCP), corrosion potential (E-corr) and the lowest corrosion current density (i(corr)) , underwent slightly localised corrosion, suggesting that the RASR process is beneficial to improve the corrosion resistance of Mg alloy.
