The modified Monte Carlo (MC) simulation of grain growth has been performed in the model applying practical orientation data to an initial microstructure. The experimental sample used in SEM/EBSP analysis was annealed sheet and foil of a pure aluminum after rolling. It was found that the samples of a pure aluminum had a general recrystallization texture in a rolled sheet. The texture became sharper during grain growth. The simulation was carried out using modified MC method by considering activated states for grain-boundary migration. The texture developed having analogy with that of experiment for the model with dependence of grain-boundary energy on crystallographic misorientation, while the texture was randomized for the basic model without the dependency.
