Re: Ferrite / Pearlite Formation

Hi Bernd,
I wanted to know if there is way to reduce the calculation time for bigger input imagesfor example a numerical method. The models work for smaller domain but they take for ever for calculation of bigger images.

BR,
Mehnoush

Re: Ferrite / Pearlite Formation

Hi Bernd, so solved the previous problem. so as a summary, we started from a image of the structure with pearlite ferrite grains and by substituting the pearlite grains with austenite we were able to some how reach a equivalent of pearlite ferrite structure (as the MICRESS examples do). Following we...

Re: Ferrite / Pearlite Formation

So i could solve the problem. However, i have a new problem. :? i only have the phase transition in the pearlite phases. although it should happen also in the ferrite. moreover by the increase of the temperature the interfaces becoms very thick and unrealistic.

Re: Ferrite / Pearlite Formation

HI Bernd, we finaly could obtain the Ferrite/pearlite structure by cooling down austenite/ferrite structure. kow we want to simulation the heating of the obtained structure with 100000 K/s but the results are not looking good. the austenite phase is formed as big massive grain also grain interfaces ...

Re: Ferrite / Pearlite Formation

Dear Bernd, I made the initial structure much smaller (Matrix size). I ran the simulation. An improvement is that we do not have the austenite phase any more at the end of the transformation time. However, the result is still not satisfying. The main problem i think is thick interfaces. also the sma...
