Effect of Lattice Anisotropy on Simulations of Grain Boundary Movement in Two-Dimensions



This paper try to elucidate some aspects of the impact of using two different types of computational lattices on the solution of simple models like, for example, grain boundary migration and/or dynamic recrystallization.Not surprisingly, the final solution is obviously affected by anisotropy of used lattices but as we know, they are computational lattices.Ho wever, a material itself has its own anisotropy of its lattice probably different from those lattices used in model.Therefore, the main task in nowadays simulations is to get rid of the influence of computational lattice and to achieve the properties of the lattice of the simulated material.
