modeling analysis of microstructure phase transformation in an alloy

Hi every one,

I need to modeling a thermal analysis of a microstructure of steel or other alloy by FEM or XFEM. so i need some metallurgical data for phase transformation.for example at which temperature or time martensit converts to austenit or etc. I also need how I can model this microstructure in abaqus that has change in boundries due to phase transformation. i appreciate if someone help me.

thanks
