Nanoscience and technology : an international journal Vol. 13, № 2. P. 23-29Abstract: In this paper, a two-dimensional model of bulk synthesis of a heterogeneous structure is proposed using a kinetic model of phase growth. The stage of nucleation is not taken into account. The initial distribution of the phase nucleation centers is given randomly. The growth algorithm takes into account the presence of neighboring grains. The phase fraction is averaged for a series of numerical experiments. Statistical analysis revealed the influence of the computational domain size and the number of phase nucleation centers on the accuracy of the values of the average integral phase concentrations.
