Questions regarding new/modified inputs for AM in Micress 7.1
Posted: Tue Nov 09, 2021 3:15 pm
Dear Bernd,
I would first like to say, it is so nice to see two examples on simulation of SLM processes (A017 and A018 applications), which serves as a solid bases for reference while we are constructing our simulations! However, there are some inputs/assumptions which I actually didn't understand what is the reason behind them. You answers will be much valuable for me to improve my simulations:
1-When I start my simulations, I receive:
# In phase BCC_B2 component CO is defined as interstitial.
# In phase BCC_B2 component NI is defined as interstitial.
# In phase BCC_B2 component AL is defined as interstitial.
As far as I understand this is automatically detected by Micress. Does that mean this elements will diffuse faster in B2_BCC phase but not in other phases? Is these selections composition dependent ?
2-I would also like to ask what is the factor 0.7 standing next to atc mob_corr refers to in A017_M247 example? I realized it is only there for FCC_L12 phase, which is the initial pahse to solidify.
3- What happens when we categorize a seed type? What is the number 11 is standing for?
# Shall categorization be applied to this seed type?
# Options: categorize {Number} no_categorize
categorize 11
4- What does the number 111 stands for in shield phase or group number?
# Shield effect:
# Shield time [s] [shield phase or group number] ?
5.E-6 111
5-What is the difference between shield and nucleation distances?
# Shield distance [micrometers] [ nucleation distance [micrometers] ] ?
0.15 0.80
6- Can you also briefly explain what does giving a penatly to a certain component in certain phase stands for in concentration solver?
7- In concetration solver I saw order/disorder term with defining sublattices. Does it somehow helps to define the so called ingredients of the ordered or disordered phases?
8. There is also diff_comp_sets and vol_comp_sets option where L12 and L12#2 phases are selected. I would also like to understand where this input can be useful.
I would appreciate your answers and thank you again for your efforts to prepare such nice application examples!
Regards,
Ahmet
