摘要	Recent synchrotron X-ray measurements examined three-dimensional boundary migration during recrys-tallization [Scripta Mater 205 (2021) 114187]. To analyze possible correlations between grain boundary mobility and the observed heterogeneous boundary migration, molecular dynamics simulations were car-ried out. Migration of two selected boundary segments were simulated in both planar and spherical bicrystal atomistic models. These two segments were chosen because in the experiment one was ob-served to migrate much faster than the other. The simulations reveal that mobility cannot account for the experimentally observed heterogeneous migration. The result points to the possibility that recrystal-lization boundary migration strongly depends on features within the deformed microstructure.(c) 2021 The Author(s).
