The intrinsic mobilities of a series of symmetrical tilt grain boundaries (GBs) in Al were simulated using a modified synthetic driving force method. Statistical analysis of the mobility data reveals that low-angle GBs are on average more mobile and show larger spread in their mobilities than high-angle GBs. GBs with axes broadly near < 111 > or boundary planes close to 1 1 0 have relatively high mobility. No visible correlation is found between GB mobility and energy. (C) 2018 Elsevier B.V.
