My fellow scientist

I am trying to do some calculations to find bainite start in steel. As you know in steels bainite form at temperatures below T0which Thermocalc can easily calculate this T0 parameter (In Thermocalc classic>poly3>advanced options>Tzero). But T0 is only calculated considering chemical component of Gibbs energy. In reality strain energy produced by the displacive transformation increases the energy of the product phase i.e. ferrite which reduces the driving force of the transformation therefor a lower temperature  than T0 is required to initiate bainitic reaction. This is similar to need for under cooling in homogeneous nucleation of solid phase in solidification. My question is how can I add this strain energy to Gibbs energy of ferrite.

Thanks for your help
