Re: Simulation of delta-ferrite/austenite solidifcation sequence under SLM conditions

Dear Bernd, thank you for your reply. I saw in forum that with Dp Micress version 6.1. it is possible to plot IPFs from .miller outputs. So, I downloaded Dp 6.1., however I am not able to open and visualise any output (the interface is quite diffent), e.g. it asks to select files to display however ...

Re: Simulation of delta-ferrite/austenite solidifcation sequence under SLM conditions

Dear Bernd, Thank you for your reply. Actually, the segmentation problem also appeared when I couple para option with bottom_temperature. However, result seem to be very similar with local_velocity option so I think I will stick with that.. but besides that, most of the problems are actually solved ...

Re: Simulation of delta-ferrite/austenite solidifcation sequence under SLM conditions

Dear Bernd, Thank you for your reply and sorry for keeping you busy. I just wanted to update you about the segmentation problem, which might reduce the effort you invest for this problem in following. I tried running simulations by keeping everything same, but only changing the redistribution behavi...

Re: Simulation of delta-ferrite/austenite solidifcation sequence under SLM conditions

Dear Bernd, Thank you for your reply and I wish you nice vacations! 1- I switched Mn and Si to paratq for delta-austenite interaction. However I kept atc mob_corr option for all elements for liquid/delta and liquid/austenite interaction assuming that some Mn should still enrich in liquid during soli...

Re: Simulation of delta-ferrite/austenite solidifcation sequence under SLM conditions

Dear Bernd, I run some simulations with the 1D temperature profile obtained by FE simulations and selected 4 connection points to describe corresponding graident and cooling rate change over the domain. The simulation stops when the temperature reaches to 1000°C. The austenite nucleation is defined ...

Re: Simulation of delta-ferrite/austenite solidifcation sequence under SLM conditions

Dear Bernd, Sometimes the answer is actually really simple.. :oops: Sorry for my lack fo attention! I somehow assumed the equilibrium input was already in wt%, therefore havent converted! Now actually I run a quick simulation with coarser grid solidifcation starts with delta-ferrite and proceeds wit...

Re: Simulation of delta-ferrite/austenite solidifcation sequence under SLM conditions

Dear Bernd, Thank you for your reply! I will integrate your suggestions and try to run couple more simulations. Regarding the Scheil simulations, I always enable fast C-diffusion in classical Scheil settings but for me, the austenite always forms after 0.90 mole fraction fo solid. Therefore I am con...

Simulation of delta-ferrite/austenite solidifcation sequence under SLM conditions

Dear Bernd, I would like to construct a simulation to observe the solidification sequence in a low alloyed steel under SLM conditions. From Scheil simulations, delta-ferrite starts to form in the beginning of solidification (hypoperitectic composition) at around 1797 K and towards the end, austenite...

Re: error #40300 and 105 while initiating Liquid/FCC_L12#2 interface

Dear Bernd, Thank you for your reply. I will try to provide you more information about the system. Moreover, I sent you my GES file and drive file via direct message. Yes, in database description they state FCC and L12 phases are modelled with single gibbs free energy curve which describes order-dis...

error #40300 and 105 while initiating Liquid/FCC_L12#2 interface

Dear Bernd, I recently saw that there is L12 phase in my as-built samples produced by SLM and I wonder whether it formed during initial solidification or cyclic heating and cooling during deposition of subsequent layers/tracks. Therefore I am trying to involve L12 phase in my solidification simulati...
