Abstract Grain boundary (GB) is an important microstructure and plays a vital role in the mechanical properties of
polycrystalline materials by GB migration and sliding. In this work, molecular dynamic (MD) simulations
were performed to investigate the migration mechanisms of 
symmetric tilt grain boundaries
(STGBs) in magnesium. A total of 15 STGBs with the rotation angle θ from 0° to 90° were studied under a
pure shear loading. The results show that the GB migration mechanisms are significantly influenced by the
GB structure. For small angle STGBs (θ<28°), the GB migration is mediated by twin nucleation from GB… More >
