Dear Bernd: I have runed the driving file and the result mekes me happy. Really thankyou for those professional changes which I can not do on my own. I want to ask something about the effective phase model: in "-phas.mcr" data pearlite phase is presented with colour blue, which means interface. That...

Dear Bernd:

I really appreciate it that you can take some time to run the driving file. I am also trying to change parameters to get a reasonable result. The corresponding .ges5 file is in the attatchment.

Thank you again and wish you a nice weekend.

Hello Bernd: Thank you for your help. A running problem occured in my simulation of the transformation from austenite to pearlite. It is a problem of "trying hard phases 3 1 level: 3 zp= 12362 errror=3". (3 is ferrite and 1 is austenite) I know that is really a frequently-occured problem. I have tri...

Hello Bernd: Thank you for your help. I searched the discussion before about the effective phase model ("unresolved") and then set the solid-solid transformation from austenite to pearlite as follows:(phase 3 is ferrite, phase 1 is austenite and phase 4 is cementite) # Input for seed type 3 (Ferrite...

Dear Bernd: Sorry I wasn't so clear about this issue. Now I begin to understand: The "unsolved" model treat pearlite as one single phase, but the cementite lamellae need to simulate both cementite and ferrite separately. If the "unsolved" model is adopted, we can not see the lamellar structure of pe...

Dear Bernd: Firstly thank you for your help! Sorry I did't express clearly. What I want to simulate is the cementite lamellae. As you told, I refered to the standard "gamma_alpha_pearlite TQ_dri" file. Like the standard file, I set austenite as substrate phase of ferrite and set ferrite as substrate...

Hello Bernd: Thank you very much for you kindly help! After the solidification I need to simulate the solid state transformation. It is an eutectiod reaction, from austenite to pearlite. According to the information I get, the transformation process may be like the picture. I really do not know how ...

Dear Bernd: Thank you for your help. I checked the TabT file and found out that it was the small time step that cause the problem. After I set the diffusion of Si in cementite as stoichiometric, the problem was solved. But there is another problem. When the phase ferrite and cementite occur, an erro...

Dear Bernd: It's me again. I used the model Janin gave me for the solidification of ductile cast iron, it works, and I have got some results. As you have said, the process of graphite forming is a very complex problem. So I am not very confident about my resuls....can you please help me take a look ...

Dear Janin:
You save me from my bachelor thesis! Really thanks~

Thanks Bernd again.
