Phase field crystal simulation of the structure evolution between the hexagonal and square phases at elevated pressures
Based on the two-mode phase field crystal (PFC) model and the principle of the common tangent, a two-dimensional PFC phase diagram is established. According to the phase diagram, the parameters for a steady growth of the hexagonal and the square phase are found. Moreover, the nucleation and...

| description | Based on the two-mode phase field crystal (PFC) model and the principle of
the common tangent, a two-dimensional PFC phase diagram is established.
According to the phase diagram, the parameters for a steady growth of the
hexagonal and the square phase are found. Moreover, the nucleation and growth
characteristics of the square phase from hexagonal phase under different
pressures are simulated by using these parameters. The movements of
dislocation core under pressure at different transformation stages are
revealed and compared with each other. Finally, by changing the grain
orientation, the formation and disappearance of grain boundaries at different
angles are simulated and analyzed. |
