Regarding getting larger undercooling (around 18K) for nucleation of FCC_L12#3.... Nucleation for FCC_L12#3 was set at the S/L interface. so using analytical_curvature was giving error, and therefore I had to use stabilization model. but I tried analitical_curvature model changing the FCC_L12#3 nucl...

I will post the answer in here https://board.micress.de/viewtopic.php?f=9&t=629

Hi Bernd,

I think its good to create a new topic for this since it might be valuable in future.

Thanks Bernd. For the phase 2, during nucleation, I get initial undercooling around 18K. I guess this is too high. ? Problem here is that the gird resolution is 2.5nm and It gives high undercooling value. Alternative would be to use a smaller interfacial energy value. but then I have to artificially...

Dear vamsi, The error you show are not very characteristic. I would look first for the following: 1.) Thermodynamic problems like apparent demixing due to the pseudo-binary approximation, or solidus/liquidus slopes which are close to 0. To find this problem, you need to check the .TabLin output. Re...

Hi,

What are the possible reasons to get the error " Thermo-Calc error 1611 MICRESS error 22 phases 1/ 1"

phase 1 is FCC_L12

I took the GB energy data form literature for Ni. There the highest value is around 1.2E-04 J/cm^2.

if it is round 8 times, is it still high?

Hi Bernd,

How can we locate error position "zp" in DP_MICRESS?

Hi Bernd Thanks again. When I check the .TabTQ, I can see 0/1 interaction time increases significantly compare to 0/2 and 1/2. I used misorientation model with constant factor (0.1) for low angle GB. My 0/1 interface energy is 1.2E-05 and 1/1 interface energy is 1.2E-04. I did not use any stabilizat...

Hi Bernd, Thanks a lot. I just checked .TabT and .TabP files between two simulations. In HAGB simulation during the time where the grains meet up the time step is in E-08 range (mostly) where as for the LAGB it varies between E-07 and E-08. I see very strong increase in TQ and PF times in HAGB simul...
