MICRESS Forum

Dear Sir I would like to know about microstructure evolution during deformation by forming operations.I read a post regarding temperature time profile given as input.How it is equivalent to get the exact microstructure by giving stress? Also,for cold forming operations without temperature time profi...

Dear Bernd, I will try to simulate with 1d temp coupling for that condition. 1.With further adding the alloying elements in the ternary system , so that to simulate single phase for an inconel superalloy system,I made the following changes in the driving file,it is running but the phase disappeared ...

Dear Bernd, Thanks for your reply.For the ternary alloy I was initially simulating was done successfully for slm conditions for small time inputs. Q1.)I want to know what temperature coupling specified in flags section can do :?: what is gs and rgbs coupling mentioned in the Temperature.dri input fi...

Dear Bernd This is the error message shown when I am trying to simulate for SLM conditions.This is because of the quasi-equilibrium problem you mentioned about earlier or some other problem :?: the velocity used is 20 cm/s. :) At the start, after grain reaches full size ,it shows the following. --> ...

Dear Bernd, Thank you for your previous replies.Sure,I will post everything in forum here after.diagonal extrapolation method helped to rectify the error of demixing :) .Now,with increasing velocities I am simulating for the same ni-cr-mo system,where for 1cm/s velocity ,the screen shows the followi...

Dear Bernd, Also,with lower cooling conditions with which a simulation I got ,has no interface area at a particular location(very little part) at the bottom...what must be the reason for that ? Micress has few modifications to be done regarding high temperature gradients and cooling rates like few p...

Dear Bernd, Thanks for your reply.So,Is there any possibility/solution to simulate such high cooling rates and thermal gradients without those databases :?: .You have any idea regarding this? :) Also at times there are warning statements like" warning of demixing of the component Cr in phase 0/1". w...

Dear Bernd,
Thanks for your reply.I will correct those and try to simulate.

Hello Sir, I am new to micress and am trying to simulate a ternary alloy system single phase solidification initially with selective laser melting(slm) process parameters which involves very high temperature gradients and cooling rates around 35000k/cm and 10^4-10^5 k/s.I am not getting a stable sim...
