| Abstract Scope |
Using our high-fidelity CPFEM model we explore the role of twin transmission and twin variant continuity in relation to grain boundary misorientation in magnesium. Twin transmission is an important plastic mechanism, an understanding of which could facilitate the wide-scale adoption of magnesium as a lightweight alternative to prevalent industry options. We demonstrate that a principle of twin variant continuity across grain boundaries is operative for specific misorientation angles relative to the c-axis but not the a-axis. It appears to be a principle of important mechanical consequence that needs to be better addressed in the literature, and this study only begins its exploration. It serves as a potential indicator of the promotion of twin transmission in the 20-40-degree range in Magnesium. We compare to an electron back-scattered diffraction image to validate the interpretation of our simulations. |
