Maximum nucleation temperature
Posted: Fri Feb 11, 2022 12:26 pm
Hello everyone,
recently, I was a little bit confused about the correct setting of the maximum solidification temperature.
I want to simulate an alloy which is made up of essentially iron and chromium. TiN (titanium nitrade) particles are used to refine the microstrucure.
Titanium and nitrogen are not included into the simulation, only the effects of these particles are represented for example with the Zener pinning effect, seeds for nucleation and so on.
My question is: Is it correct to set the maximum nucleation temperature to the liquidus temperature of the alloy minus the necessary undercooling temperature to have grains forming at the seeds?
My concern is, that I don't want to set a lower solidification temperature, when MICRESS already considers necessary undercooling, for example.
As always, I am looking forward for your replies!
Best regards,
Moritz
