Physical modelling of phase transformations in high strength steels
In the model presented, phase transformations in steels are described using thermodynamic and kinetic laws at the scale of an austenite grain. A single geometric treatment leads to the final transformed fraction. The effect of composition, temperature path and austenite grain size is taken into account. The predictions of the model are compared with experimental results concerning different steel grades. The results obtained for ferrite, bainite and final ferrite grain size are encouraging.
