Abstract
Based on the CALPHAD method, a thermodynamic description of the Fe–M–V–NB–Ti–C–N system (where M is Al, Cr, Mn, Ni, or Si) has been constructed and, using this description, the solubilities of carbonitrides in austenite for low-alloy low-carbon steels with V, Nb, and Ti have been calculated using 10G2FB steel as an example. The influence of the alloy composition and temperature on the composition and amount of carbonitride phases and on the concentration of these elements in the solid solution has been analyzed.
