Re: entropy difference between two phases

Hi Bernd, I want to compare effect of transformation mode e.g. para and nple on kinetics. Then I need the linearization parameters by coupling ThermoCalc with Micress. How can I get them when para-equilibrium is assumed? So far, I found the linearization parameters are the same for para and nple, i....

Re: Artifact?

Hi Bernd,

Yes, Now I am using Version 6.
A question: for those output files e.g. intf, c2ha3, driv, what's the cutoff, phasemin? Is that the same for outputs of TabC file?

Thank you.

Ben

Re: about some numerical parameters

Hi Bernd, I got the mobility from simulation considering carbon diffusion, then applied it to simulation considering manganese diffusion. Maybe I can reduce the magnitude of mobility with some tests proving that diffusion control is reached, mobility has little effect on kinetics. Do you think I sho...

Re: about some numerical parameters

Hi Bernd,
I am do simulation involving Mn diffusion. Since I use a high mobility, the time step for phase-field solver is smaller than diffusion time step.
will it cause a numerical problem? Does the diffusion time step have to be set the same as phase-field solver in such a case?
Thank you.

Hi Bernd,

Maybe I used TCR to create the GES file previously. Now I have attached the one created by TCS.

Re: Artifact?

Bernd, We do not have Thermo_calc installed on the Linux server. I don't know how MICRESS calls TQ as the old version 5beta can do this. One of my colleagues said something about calling TQ on another Windows computer. I have attached my simulation files. Could you please try running the simulation ...

Re: Artifact?

Hi Bernd,

Thank you and Ralph.
I can run MICRESS6.3 now.
However, I got the error:
Sentinel RMS Development Kit: Error[17]: Probably no servers are running on this subnet.
TQ initialization failed(no license?)

Problems with installation of version 6

Hi Bernd,

we do have version 6. Unfortunately, it is not well installed for linking to TQ .
I discussed via email with you a few months ago. Unfortunately, the administrator of our computer did not solve it.
That's why I am using 5. :(

Re: Artifact?

Hi Bernd, Unfortunately I am using version 5beta :( . Maybe this is the reason why I got the artifact. By the way, how can I get paraequilibrium thermodynamic data[entropy, slope etc] from MICRESS[with TQ database]. I found that regardless of nple or para setting, the thermodynamic data in the *.log...

Re: Artifact?

Hi Bernd, It is the phase concentration (Mn in austenite). The redistribution_control is chosen as C-normal, Mn-nple. The interface is migrating. As you said, I expected the phase concentration profile should have been a horizontal line equal to nominal Mn concentration. however I got a positive spi...
