Re: how to turn off the Gibbs-Thomson effect

Dear Bernd, Thank you so much for your kind help ! Our results are similar to you ! Maybe the interface missing at the initial stage is not an important matter. But may I ask why the migration rate of the alpha/gamma interface (middle part) is so slow ? it seems not consistent with the experimental ...

Re: how to turn off the Gibbs-Thomson effect

Dear Bernd,

Thank you so much for your kind help !

We have tried it one more time but the results still seems un-normal. I have sent the in.file to you. Please check it~

Thank you again for your kind help ! We appreciate you so much~

Regards,

Sai Li

Re: how to turn off the Gibbs-Thomson effect

Dear Bernd, Thank you so much for your kind reply ! I have sent the dri.file to you~please check it ! As a matter of facet, we just changed the shape of the grains compared with the spheral model (we have discussed before). But it is very strange that the interface is missing at the planer model. Th...

Re: how to turn off the Gibbs-Thomson effect

Dear Bernd, Thank you so much for your kind reply and help ! We have incresed the cells number of the interface but it is still as the previous image. But when we changed the Mn (component 2) from the nple mode to 'normal mob_corr' mode, the interface would occur. May I ask what we should do (or whi...

Re: how to turn off the Gibbs-Thomson effect

Dear Bernd, Thank you so much for your reply ! The initial microstructure is attached, it is symmetry. The red part is austenite. And there is no temperature changing in whole system. what you mean is that it is reasonable ? Or we have to adjust teh parameters to make the microstructure symmetry? Th...

Re: how to turn off the Gibbs-Thomson effect

Dear Bernd, Thank you so much for your kind reply and program !! It runs very well and much more quickly than the previous one ! We appreciate your help very much ! But there is a new problem when we change the system to the lamellar pearlite. The results show a dissymmetry phenomenon even if we set...

Re: how to turn off the Gibbs-Thomson effect

Dear Bernd, Thank you so much for your kind email ! The program is sent you by the private message, please check it ! The question is the values of 'Kinetic coefficient mu between phases 1 and 2 (1 and 3; 2 and 3) [ min. value ] [cm**4/(Js)]'. If we set 1, 1 and 1e-3, respectively . There would be a...

Re: how to turn off the Gibbs-Thomson effect

Dear Bernd, Thank you so much for your kind reply ! I understand the numerical artifacts for setup, but is it possible for us to get the background principle and calculation process for MICRESS so that we could find the meaning for each parameters ? Thank you again for your kind help! Regards, Sai Li

Re: how to turn off the Gibbs-Thomson effect

1.PNG Dear Bernd, Apology for the unclear description and late reply ! The attachment is the sketch of the simulation. We did the two kinds of model, the difference of them is only the geometry of the cementite and austenite (I is plate and II is circle). But in model I, the carbon concentration at...

Re: how to turn off the Gibbs-Thomson effect

Dear Bernd, Thank you so much for your help !! We rechechk the results, the carbon content near the cementite indeed higher than the matrix alpha! But we found a new problem...when we simulated the austenization from the cem+bcc microstrucure (austenite nucleate at the cem/fer nterface and the growt...
