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 of various types of grain 
boundaries are quantitatively characterized in terms of its respective grain boundary 
energy dissipation. The simulated ferrite fraction agrees well with the expectation from 
phase diagram, which verifies this model.},
