Thermodynamics in steels at temperatures lower than A1
Posted: Sat Jul 30, 2011 8:11 pm
Hi there,
I made some gamma-alpha simulation in a steel at 680°C. Its chemical composition is 0.07%C, 1.44%Mn, 0.15%Mo. I put the GES file from ThermoCalc to MICRESS. When I made the GES file, I select the phases fcc, bcc, liq and cementite. Therefore, in principle, the A1 line must appear if there is cementite. Below the A1 temperature, it will be no austenite.
I wonder very much, how MICRESS calculate the composition of the austenite in my simulation at 680°C-under A1 temperature.
Thanks again
