Abstract Based on multiphase field conception and integrated with the idea of vectorvalued phase field, a phase field model for typical allotropic transformation of solid
solution is proposed. The model takes the non-uniform distribution of grain boundaries of
parent phase and crystal orientation into account in proper way, as being illustrated by the
simulation of austenite to ferrite transformation in low carbon steel. It is found that the
misorientation dependent grain boundary mobility shows strong influence on the
formation of ferrite morphology comparing with the weak effect exerted by
misorientation dependent grain boundary energy. The evolution More >
