Re: How grain boundary diffusion works

Hi Bernd

when you have set the parameters correctly, the D_GB physical out put in .diff file should be larger than the bulk diffusion coefficient value ?

Re: Data for further nucleation

that would be OK, I think. we can give it a try

Re: Data for further nucleation

Ahh.. Thats a problem for me then. :(

Will it take few months to fix it?

Re: Data for further nucleation

But since the boundary create between the solid phase and "switched-solid" phase will be a boundary with 0 degree misorientation. right?

So there will only be one grain boundary with misorienation. ?

Re: Data for further nucleation

Hi Bernd, I will send the files to you. In my simulation I have two gamma seed types with two orientation. during the solidification it will create a grain boundary. Once after switching my intention is only to have one grain boundary. So I want to make remaining liquid orientations to be same orien...

Re: Data for further nucleation

Hi Bernd, It did not seems to work as expected. The switched grains still have the orientation of the liquid phase. then I tried changing the reference phase to solid phase (1) and substrate phase to liquid (0). There also switched grains have orientation of liquid phase. in both cases I used "paren...

Re: Data for further nucleation

thanks Bernd. So is this the correct way of defining?

Re: Data for further nucleation

Hi Bernd, when you switch the remaining liquid in a simulation to a solid phase (using nucleation at interface of the solid phase) is there a way to set the orientation of the newly created solid phase to take the same orientation as the parent solid phase orientation? I do not want to create and in...

Re: Simulation of solidification of Gamma prime alloy during SLM process

Hi Bernd, In my simulations I mainly get error to wards the end of the simulation where small amount of Liquid (>0.02%) is present. So I did some single phase equilibrium calculations with thermo-calc. considering the liquid composition. What I see is depend up on the temperature, major constituents...

Re: Grain Input

Thank Bernd,

Also is there a way to extract the coordinates of the grains that created when we use the option "random" for "type of grain positioning"

In addition to that, if you are reading grain properties from a file, how should this file looks like? (I am using angle_2d for orientation)
