Initial Concentration
Posted: Tue Dec 06, 2016 2:38 pm
Hello,
i want to simulate the following phase transitions:
Ferrite/Pearlite -> Austenite (heating)
Austenite -> Martensite (fast cooling)
It is well known, that there is no way to represent Pearlite as a separate Phase in Micress. Because of that, it seems to be very difficult to set a FP strucuture (as a mixture of Ferrite and cementite) as initial strucuture.
I changed some settings in the GammaAlphaPearlite_TQ example (initial composition, cooling rate) and my idea was, to set the last "step" of this example as initial for my first simulation. But how can i do that?
I tried it with the "restart" -function. But for that, i need some further informations:
1) what does the "shiftX , shiftY .." mean?
2) when i try to to it that way, what about the initial concentratin input and grain input, etc? is everything replaced by the inputs of the restart_file?
3) what about the diffusion input?... what i want to know is, is it possible, to change the diffusion input data in the "second" simulation? (when in the "first" simulation, the diff. input was coupled to TQ, is it possible to set it in the "second" simulation manually?
Are there any other ways? I think, it is not possible to use those ASCII-Files, because of the carbon concentration, or am i wrong?
It would be great, if someone has some helpful ideas
Furthermore, is it possible to start a "noTQ simulation", from a initial strucuture of a "TQ simulation" ?
Best regard
