A new phase field model has been developed which can simulate the
austenite to ferrite (gamma --> alpha) transformation in low
carbon steels at large space and time scales and involving multiple
ferrite grain growth. The two-dimensional phase-field simulation
shows that interface composition does not obey the local equilibrium
assumption, while grain growth obeys a parabolic law for most of
the transformation. The kinetics of continuous cooling transformation
are successfully modelled. Results suggest that nucleation occurs
both along austenite grain boundaries and within grains for high
cooling rate transformations. Grain coarsening behind the transformation
front is predicted. Two interesting phenomena, namely, interface
acceleration, and solute enrichment behind the impingement fronts,
are disclosed via this phase-field simulation.
