| Abstract Scope |
Deformation behavior of magnesium single crystals was examined in this study. Single crystals of pure magnesium and magnesium alloys were prepared by the Bridgeman method. The single crystal specimens with different orientations were deformed at various temperatures in order to determine the critical resolved shear stress (CRSS) values for various major slip and twin modes. The deformed samples were examined with optical and scanning electron microscopy. The visco-plastic self-consistent (VPSC) simulation was carried out in order to obtain the CRSS and hardening parameters for various deformation modes, when multiple deformation modes were involved in plastic deformation due to the loading direction of a single crystal specimen. The change in orientation due to plastic deformation and/or recrystallization was also examined. |
