Re: Is it possible to simulate both recrystallization and precipitation process at the same time?

You should do that, because the problems could also have other reasons, e.g. - the carbides start with the wrong composition set (i.e. with fcc composition). Then they would desolve in any case due to curvature. You should check the initial linearisation in the .log file to be sure this is not the ...

And the precipitates would grow if you hadn't recrystallisation at the same time? You tried that?

Bernd
Thanks for the Response. I don't know if they would grow without recrystallisation. I didn't try that.

Re: Is it possible to simulate both recrystallization and precipitation process at the same time?

Hi Junzhen, Wanted to answer to your question, but it seems you just removed it... I would guess it is the interface energy which is too high so that the seeds vanish. Bernd Ahh...sorry and thanks for the Reply. The problem is that when I am trying to simulate the precipitating process with recryst...

Precipitation phase dissolve back into matrix during simulation

Hi, I have a Problem when I am trying to simulate the precipitation during cooling process. I indeed define the nucleation of precipitation Phase, however, the precipitates dissolve back into the matrix during the Simulation process. Part of input is shown below. Did I set any wrong parameter? # Inp...

Hi, Bernd,
Thanks so much for the reply.
I will try the restart function.
Thanks again for your help.

Re: Is it possible to simulate both recrystallization and precipitation process at the same time?

Hi, Bernd, Thanks for your Reply. I generated 1_87.vtk file from a prior simulation using DP_MICRESS. And I changed the Header according to examples. Then I tried to Input it as a initial microstructure of the second Simulation. It aborted with an error in the input stage. I asked one of my colleagu...

Re: Is it possible to simulate both recrystallization and precipitation process at the same time?

Hi, Bernd,
As said in the Vol3 manual, we can get the .vtk file by the post-peocessing using DP_Micress.
Then I tried to use the .vtk file I got through DP_Micress as the Grain Input. But it didn't work.
Could you explain it a little bit ?
Thank you very much.

Re: Is it possible to simulate both recrystallization and precipitation process at the same time?

Hi, Bernd, thank you for your timely reply. I have another question about precipitation caculation. My steel contains more than ten Elements, like Fe, C, Mn, si etc. However, only two or three elements are involved in precipatation. Should I input all of the elements in my steel when i am trying to ...

Re: Is it possible to simulate both recrystallization and precipitation process at the same time?

Hi, Bernd, thank you so much for the reply. I learned much from your reply. When I am trying to simulate recrystallisation, minimum and maximum of recrystallisation energy are required. When the values of them are smaller than energy threshold of recrystallisation energy (stored energy), no recrysta...

Re: Is it possible to simulate both recrystallization and precipitation process at the same time?

Hi,Bernd Thanks for the response. That is very helpful. I have another question. In the recrystallisation simulation, is the energy shreshold for recrystallisation model equal to the stored energy? I know literally that the driving force control the growth of grain. However,except for temperature, w...
