摘要: Mg–Zn solid solutions have been reported to show 14–21% tensile elongation after rolling and annealing, but their textures exhibit strong basal texture similar pure Mg. This phenomenon contrasts with the case in Mg–Y showing good RT ductility weakened textures. To reveal mechanism of at RT, we investigated effect Zn on Mg alloys using atomistic simulations. The simulations that can activate slip by reducing critical resolved shear stress anisotropy among systems, thereby improving ductility. It is also found grain boundary segregation tendency low. known affect twinning recrystallization which modify evolution process. From low Zn, are expected yield a
