Zn-Al solidification

Dear Bernd Today, i have a question about the Solidification of Zn-Al. I make a GES file. And i did Sheil simulation to see which phase i should consider for phase field simulation. Unfortunately, mob2 database in the Thermo_Calc. does not have mobility information of Al and Zn in the specific phase...

Re: Error during simulation

Dear Bernd Thank you for your reply!! :D It seems that the simulation is now going well. I have some questions about input dislocation density in recrystallization simulation. In the phase data part, i have to put "dislocation threshold for recrystallization" and in the seed data input part, there i...

Error during simulation

Dear Bernd Recently, i try to simulate both of recrystallization of ferrite and formation of austenite during intercritical annealing process. So i made a driving file as attached. However, the simulation always stopped at 6 seconds. Is there any way i can see what the problem is? I attached all the...

Partioning issue

Dear Bernd I have a question about partitioning of Si during solidification. Is there any way i can put partitioning coefficient in MICRESS? I found that in FeCMnAl system, Si is always partioned into liquid phase when i do thermocalc coupling simulation during solidification. I want Si to reside in...

About solute drag

Dear Bernd Long time no question about MICRESS ;) Today i came back to ask about solute drag model in the MICRESS. First of all, I want to ask about the meaning of each line in the dri file as given below. ... # Options: constant temp_dependent dg_dependent temp_dependent # File for kinetic coeffici...

Re: Solidification simulation under casting

Dear Bernd I finally finished a simulation with high resolution. I think that it task around a month to get this result :) I cooled the domain for 3000s to 746K and reheated at a rate of 20K/s. If i apply the interface mobility between ferrite and austenite which is literary taken, i found that no f...

Re: Solidification simulation under casting

Dear Bernd Thank you for your reply! Firstly, NPLE or Para equilibrium assumption is not proper for my simulation since i heat up the domain to 1550k which is the temperature any elements can diffuse with high speed. Many researchers including R. Wei et. al. (Metallurgica and materials transactions ...

Re: Solidification simulation under casting

Dear Bernd How have you been? :D Long time no questions about my simulation;; So far i simulated very long cooling time and i finally get the result. After cooling, i reheated my simulation domain at a heating rate of 20K/s. However, although i did the simulation which is closed to the real situatio...
