Abstract Scope |
Mg-Li system alloy has excellent formability at room temperature due to their crystal structure. However, exfoliation corrosion appears during progress of corrosion. Therefore, it is difficult to apply for the actual metallic products without corrosion protection. Previously, the suppression of exfoliation could be attained by recrystallization of cold-rolled alloy. The microstructural characteristics were completely changed by recrystallization, so the detailed investigation is required for explanation of exfoliation corrosion origination. In this study, the origination of exfoliation corrosion of Mg-14 mass%Li-1 mass%Al alloy with various microstructures such as as-rolled, only recovered and recrystallized state. As the results, the induced strain during severe deformation is major factor of expression of exfoliation corrosion. |
