The macroscopic behaviour of materials is strongly determined by their mtcrosiruclure. Within this scope grain size and texture play an important role. Therefore it is-of great interest in materials science to understand and to predict grain growth and texture evolution during annealing. Many efforts have been made to simulate grain grdwth, either to confirm well known theoretical assumptions or to compare simulation results with experimental data. Since most of the grain growth theories [1-3] lead to a parabolic igtain growth kinetics of the form R=ktn, (1) with n=0.5, the fulfilment of this law was taken as one criterion whether a simulation procedure is able ttulcscrihc normal grain growth or not, even if the value n = 0.5 is hardly found by experiments.
