Title: Effect of grain boundary energy anisotropy on highly textured grain structures studied by phase-field simulations Authors: Chang, Kunok ×Moelans, Nele # Issue Date: 2014 Publisher: Elsevier Science Series Title: Acta Materialia vol:64 pages:443-454 Abstract: Two-dimensional phase field simulations were performed of grain growth in highly textured materials with equal fractions of 2 texture components, denoted as $\alpha$ and $\beta$ grains, and assuming 2 values of the grain boundary energies, namely $\sigma_{low}$ for the boundaries between grains of a different texture component and $\sigma_{high}$ for boundaries between grains of a similar orientation, resulting in microstructures with alternating $\alpha$ and $\beta$ grains and stable quadruple junctions. For different magnitudes of the anisotropy in grain boundary energy $R=\sigma_{high}/\sigma_{low}$, the occurrence of the different types of triple and quadruple junctions and the distributions of the normalized grain size, the number of faces per grain, the normalized grain boundary length per grain and the dihedral angles at grain boundary junctions were investigated.
