Re: Initial Concentration
Dear Bernd, since my simulation of austenitisation works (by the way: your approach was very helpful - thank you !) i want to simulate martensitic formation. But i got another problem. Because of the complicated circumstances, my explanation could be confusing. so i will try to explain as simple as ...

Re: Reg. Modeling of alpha-gamma transformation
Dear Bernd, i increased the heating rate, because our final target are heating rates about 1E6. But it doesn´t matter in this case and for this simulation. I decreased the heatingrate to 1250K/s. Furthermore i matched the time intervals. Nevertheless, i nearly receive the same result as before. Exce...

Re: Reg. Modeling of alpha-gamma transformation
Hi Bernd, thank you for your helpful answer. My simulation-output looks much better. Nevertheless i got two last questions(hopefully "last" :lol: ). I matched the time steps, the mobility (like you mentioned above) and furthermore i increased the cooling rate. Now the seeds austenite seeds are growi...

Re: Reg. Modeling of alpha-gamma transformation
Dear Bernd, i´m sorry for my late reply and for my vague question. I try to model the austenite formation of a low carbon steel. My first problem was to represent the ferrite-pearlite structure. So i thought it would be a good idea, to use the final structure of the GammaAlphaPearlite-Example as the...

Re: Reg. Modeling of alpha-gamma transformation
Dear Bernd, i also tried to simulate the austenite formation, but i cant reach a useful result. My target is, to simulate the formation of austenite with a high heating rate. Because of that, i thought it would be better to start the first simulation with a low heating rate to approximate to the tar...

Re: Initial Concentration
Hello and a happy new year, i use the Micress version 6.200(windows). I changed the things you told me, but i got the same error-message as before. I tried to run the same process, but with a thermocalc coupled simulation. the error message i got here, is : unable to read from file [...] STOP in rou...

Re: Initial Concentration
Hello, thank you for your reply. I have a further question. When i run the simulation with the "structure_only" option, micress gives me the following errors: http://www2.pic-upload.de/thumb/32322256/Micress_errors.png what can i do against this problem ? Do you need more information about the input...

Re: Initial Concentration
Additional Information:
when i try to run the simulation with this restart option, following error occurs:
what does that mean? Or why is it possible to read all informations except the nucleation data?

Initial Concentration
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...

Martensitic Transformation
Hello, 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 Mic...
