Re: Solid state transition

Dear Krishnendu, When using "paratq", a para-equilibrium model of Thermo-Calc is used when calculating quasi-equilibrium in MICRESS. That means, paraequilibrium is fully treated within Thermo-Calc, while MICRESS interprets the results as quasi-equilibrium. "para" is a MICRESS-internal model which ch...

Re: MICRESS Training

Dear Lv Shaojie, I will try to give answers to your questions: 1.) The training example T14 is already quite old and needs some rework. As far as I remember, the third phase should be cememtite, but given that the input file uses user-defined linearized phase diagram data, it also could resemble pea...

Re: Solid state transition

Dear lvshaojie, 1.) All the options you mention are special options for redistribution and available by use of the "redistribution_control" keyword. nple, para and paratq are redistribution options for elements which are diffusing slowly and cannot be spacially resolved in a MICRESS simulation. They...

Re: Solid State Transition Case

Hi lvshaojie, Your assumptions are correct: As the names imply, both examples treat gamma to alpha transformation in steel. While T010_Gamma_Alpha_dri does not include anisotropy, T015 makes use of the misorientation model to allow for the description of a (tetragonal) acicular ferrite morphology. W...

Re: MICRESS case

Dear Lv Shaojie,

Looks as if there was no free license available at that moment...

If this problem persists, and there is no logic explanation for the license usage, we need to ask Ralph for help.

Best wishes

Re: Solid State Transition Case

Dear lvshaojie, all solid phases have some sort of anisotropy, depending on the symmetry of their crystal lattice. However, we use phase anisotropy in MICRESS only in cases where we want to model a specific effects which are related to this anisotropy. In example T015_Gamma_Alpha_FeC_Acicular_dri we...

Re: Example Reset

Dear SteelOx,

Probably the version of the examples you took from our website do not conform with your current version of MICRESS. Which is the version you currently use? You can see that in the header of the .log -file output.

Re: MICRESS program

Dear Lv Shaojie, Your questions are quite general and need some concretisation. Depending on the real process you consider, there are many aspects of combining grain growth and precipitation: Typically, the first grain structures which appear during material processing are those coming from the soli...

Re: Smoothening of grain boundaries

Dear Khushbu, Welcome to the MICRESS Forum! The simplest method to smooth out an initial microstructure (wherever it comes from) is to use the initialisation steps which you can define in the section "Numerical parameters" under "Phase field solver": #Number of steps to adjust profiles of initially ...
