ThermoCal coupled problem, NPLE and no_TQ problem

Dear MICRESS team, I am making a ThermoCalc coupled problem these days on the gamma_alpha transformation of Fe-C-Mn-Mo-Si-Cr-Al at 680°C and have the following questions: 1. In the dri. file, section phase diagram, there is an option 'database[local/global], # Input of the phase diagram of phase 1 a...

Re: input of minimal and maximal rex energy

Hallo Bern,

but what's the difference of the min and max rex energy and the 'critical recrystallisation energy'?

Many thanks and best regards

separated intervals of simulation

Hallo MICRESS team, first of all I wish you merry Christmas and a happy new year. Wish you also a big progress in further program development. Today I have a question about separating the simulation into a few separate temperature profiles. In my experiment, I quech down the austenite with high cool...

Diffusivities matrix

Hallo I have a question about the diffusivity matrix in DICTRA/MICRESS. One can directly obtain the diffusivity matrix in DICTRA which is needed for the Fick's first law. For carbon flux in steel, for example, the concentration gradient of other alloying elements will affect the carbon diffusion flu...

stored energy in deformed austenite

Dear Micress experts, you know that the deformation in austenite accelerates the gamma-alpha transformation very much. On one hand, it increases the number of ferrite nuclei, which we can assign as the maximum number of new nuclei. On the other hand, the higher number of dislocation raises up the de...
