摘要：
The influence of heterogeneous arrangement of nucleation sites and non-simultaneous appearance of nuclei during recrystallization on size distribution of recrystallized grains is studied by computer simulation. It is shown that the log-normal distribution in two-dimensional microstructure can be obtained at a certain combination of nucleation characteristics. A possible role of the other parameters of recrystallization process in microstructure development is discussed. Despite the nucleation heterogeneity, the kinetics of recrystallization is shown to obey the Avrami equation. It is supposed that the shape of the grain size distribution should be used as a characteristic which proves the correctness of any recrystallization model.
