A Monte Carlo (MC) procedure was applied to study static recrystallization processes. The initial microstructure, stored energy and orientation within each grain were taken from EBSD measurements. Site orientations used in the model may change continuously in Euler space. Several types of site saturated nucleation were implemented in the model. A standard MC algorithm was used and tested in several ways. The grain size distribution and final recrystallization texture obtained from the model were compared with experimental ones. The agreement between both sets of data is satisfactory. As some minor experimental effects are not observed in the model, some improvements are finally proposed.

A modified Voronoi model is established based on the Richards method to generate 2D non-equiaxed initial microstructure for Monte Carlo simulation. Microstructures produced by the ordinary Voronoi model are isotropic and cannot reflect the effects of the deformed grain shape on the annealing process. The modified Voronoi model based on ellipse set can be used to construct the deformed microstructure. The initial microstructure reflects the mean strain and the grain size distribution follows lognormal distribution.
