MICRESS Forum

Hello,

I was wondering whether it is possible to simulate in MICRESS the austenite to pearlite phase transformation in a steel containing vanadium.

Kind regards,
Vitoria.

Dear Bernd,

thank you for your reply. Indeed our input files are very similar and by changing the grain radius to 0, the nuclei could grow as wanted.
That already solves most of the issues.
Thank you for the suggestions.

Kind regards,
Vitoria.

Dear Bernd,

the orientations and interface energy seem to be the same.
Also, the MICRESS versions are the same.

Kind regards,
Vitoria.

Dear Bernd, it is difficult to explain here what's happening but basically, I have different results in Windows and Linux which are apparently expected. However, now that I know that it should behave differently I still can't understand why some of my seeds (seed 2) nucleate at the beginning of the ...

Dear Bernd, thank you for your reply. Actually, I think that the issue might not be related only with the actual nucleation sites but with the nuclei that are not growing as well. I have three seed types: seed type 1: can nucleate since the beginning of the simulation at the colony boundaries seed t...

Dear all, I am recently trying to run some simulations using Linux and I noticed that the results that I obtain are very much different when compared with the simulations I ran in Windows. The reason why I am running simulations in Linux is to run multiple parallel simulations using the cluster. I c...

Dear Bernd,

thank you for your reply.
We actually tried using the exact 25at% value in cementite but we still have the same error.
I will send you the files in a private message.

Kind regards,

Dear Bernd,

thank you for your reply.
If I set the initial composition to be the same as the equilibrium the simulation works fine. However, I would like to use the values obtained from APT.
My question is: is that currently not possible in MICRESS?

Kind regards,
Vitoria.

Hello, I've been trying to simulate the austenite formation from an initial pearlitic structure. For the initial microstructure, I do consider the cementite lamellae. For my last simulations, I set the initial concentrations of each phase based on APT measurements instead of the equilibrium concentr...

Dear Bernd, I've been trying to simulate austenite growth in pearlite. I've been trying to match my simulations with what I've observed experimentally. The best fit was obtained with the simulation attached (cb-200Cs-19). As you can see I have two types of growth: at the colony border and inside of ...
