Re: Segregation

Hi Martin, A good check whether the results are realistic or not is to compare to a Thermo-Calc Scheil simulation which I did with the alloy composition you specified: Scheil_all_phases.PNG As you can see, the Al composition in the melt is increasing until GAMMA_PRIME is formed, then it is decreasin...

Re: entropy difference between two phases

Hi Ben, whether you see the compositions of the dormant phases or not is just a question of the exact options for the list_equilibrium command in Thermo-Calc: It looks like list_equilibrium ... Options /VWCS/: <option(s)> You can specify 4 characters, default is VWCS. They mean: Fraction order: V me...

Re: Error message during simulation

Hi Hirosaito, if the error messages which you showed appear in this order, then there obviously is already a problem occuring for phase interaction 0/1 before phase 2 is nucleated: try hard phases 0 1 trials: 2 zp= 1124 try hard phases 0 1 trials: 4 zp= 2831 CALFUN:Error4 1 0 1611 CALFUN:Error5 1611...

Re: Construction of GES

Hi Taka, it seems really to be an incompatibility of the two databases - interestingly, as I heart, it occurs only with TCS and not with TCR... So, I can only advise you to do one of the following: - don't use diffusion data for the LIQUID phase which probably makes the trouble (the values are anywa...

Re: Construction of GES

Hi Taka, technically it should work like you did - what was the problem you experienced? I personally have no experiences with FE-DATA. Sometimes it happens that the databased which you join are not compatible... Which TQ version are you using? This can also have an effect in case of incompatibiliti...

Re: Error message during simulation

Dear Hirosaito, Welcome to the MICRESS forum! The error message which you got is an internal Thermo-Calc message which is indicating that in an equilibrium calculation convergence was not possible. This is typically the case when the MICRESS simulation creates unphysical situation with compositions ...

Re: MICRESS 6.0 released

Hi Martin, It is correct what you say: If you define (in seed type 1) that phase 2 should be "unresolved", and the substrate phase is 1, then, upon nucleation, the grain of phase 1 which will be locally found will serve as partner for the new seed of phase2 to form a diffuse "pseudo-grain". The orie...

Re: MICRESS 6.0 released

Dear Martin, according to the error message in the .log file, the input "unresolved" seems to be not recognized! The ultimate check is if you input a REAL value in the next line for the "Microstructure size" which is required by the "Effective Phase" model: Your code should stop there if the "unreso...

Re: Austenite to pearlite transformation in steel

Dear sudi, it is correct to use cementite as substrate phase for nucleation of ferrite at the cementite/austenite interfaces, and ferrite as substrate phase for nucleation of cementite at the ferrite/austenite interface. The choice of the substrate phase (if it is different from the matrix phase) re...
