Description
Summary:Due to the hexagonal close-packed (HCP) crystal structure of Mg, the plasticity is poor at low temperatures. In order to solve this problem, the in-depth researches on various deformation modes of Mg are very necessary. However, there are many limitations to study these deformation modes in Mg polycrystals owing to the effect of grain boundaries, etc. It is more reasonable to conduct the researches in Mg single crystals, especially investigating the influence of crystal orientations, and the advantages of Mg single crystals are prominent particularly. On this basis, various investigations in Mg single crystals are carried out thoroughly in recent years, such as the critical resolved shear stress (CRSS) calculation, the slip and twinning modes activation determining, recrystallization behaviors and so on. In order to make clear the research advantages in Mg single crystals, a critical brief summary is conducted in this paper. Besides, various crystal plasticity finite element modeling (CPFEM) and electrochemical corrosion used in Mg single crystals are also reviewed. Finally, the current challenges and possible research directions are proposed.
