| Abstract | ||||
| A quantity of vital engineering materials is example of two-phase materials in which each phase may be polycrystalline. In numerous cases, both phases of these materials may undergo grain growth which may affect their electrical and mechanical properties. Therefor, substantial efforts have been devoted to understand the microstructural evolution of polycrystals to improve their performance in microelectronic industries. Numerical method based on Monte Carlo Potts model is used to investigate microstructural evolution of two-phase polycrystalline materials in which grain growth in both cases is controlled by grain boundary diffusion (n=4). It is shown that the microstructural evolution of two-phase polycrystals eventually reaches an asymptotic regime in which grain growth in both phases is coupled due to Zener pinning and obeys a power-law relationship d~t1/n . This conclusion is valid in a broad parameter range and is compatible with theoretical predictions and laboratory experiments. | ||||
