MICRESS Forum

Hi Bernd, thanks for your reply. So far, everything is based on experimental observations (microscopy). All these grain boundaries have misorientations >15 degrees and there shouldn't be significant difference in composition (my material is microalloyed steel so it will be difficult to experimentall...

Hi all, I am simulating austenite formation during intercritical annealing from a ferrite matrix. Nucleation of austenite occurs predominantly at ferrite grain boundaries. Based on my experimental observations, certain ferrite boundaries will not get nuclei. I wonder if there is a way to simulate th...

Hi Bernd, thank you very much for your reply. With mob_corr my kinetics make more sense. Now under NPLE for Mn and "normal mob_corr" for C, I am able to replicate my DICTRA result (see the plot attached; red curve is the MICRESS result) even after the NPLE-PLE transition. NPLE_PLE_transition_1075_ov...

Hi Bernd, I have some further questions on a similar system, although not on phase diagrams. I am running (once again) 1D α-to-γ tests on Fe-C-Mn ternary systems with TQ coupling. Under diffusion control, kinetics is usually fast at the beginning (C-diffusion controlled and close to NPLE), reaching ...

Hi all, I have tried to start on the TQ coupling function of MICRESS (v6.402 on a linux-based computing cluster) and I started with the AlCu example. I obtained a GES5 file from ThermoCalc 2019a. However, an error message occurred saying "TQ initialization failed!" without more specific explanations...

Hi Bernd,
Thanks for your suggestions! After some tweaking I found that changing the composition in phase 2 is the most effective way to avoid this artefact. Apparently I forgot some basic principles and used unreasonable numbers in my previous simulations.

Here in another simulation of mine where I also included Mn (component 2), a similar artifact occurred. This time however, the interface appears to be very thick and I cannot see the austenite slab in the middle.

Hi all, I have encountered a possible artefact. I am trying to simulate austenite formation from ferrite with a simple 1D, isothermal model (input files attached). Initially both the parent ferrite (phase 1) and austenite have a nominal C concentration of 0.039 wt%. When I start a simulation at 1100...

Hi all, I have recently changed to Linux but I cannot seem to run DP_MICRESS using the .tgz file downloaded from the main website. I tried to run it in terminal but it tells me something is wrong about shared libraries. I Use OpenSUSE Tumbleweed; one of my colleagues running Ubuntu cannot run DP_MIC...

Hi Ralph, I had a try a few minutes ago and it is fixed in the latest version.

Thank you very much!
