we try to simulate the microstructure evolution during a cooling process in a heat affected zone of a low carbon steel. We expect a martensitic structure because of the high cooling rates (about 500-1000k/s).
My first question is, is it possible to couple TTT Diagrams from ThermoCalc with Micress? Because, i think the "normal" Phase diagrams, calculated by TC, only include stable phases in equilibrium.
Obviously, Martensite is a metastable phase, so i think MICRESS can´t get the necessary informations for martensite.
If it´s not possible, is the only way using the linearised phase-diagram?
In a paper,written by R.G.Thiessen, martensite was modeled like a supersaturated bcc-phase. Is there another way to describe martensite in Micress?
And my last question is, how can I identify Martensite in DP_Micress? I think i will not see the lamellae-structure, which is typically for martensite, is that right?
And furthermore, what about the option "add_to_grain"? In the handbook for micress, i read, that this option is useful for modelling the martensitic transformation. But i really didn´t understand what it means and what this application will do? what further information needs micress, after i wrote
