摘要

In this investigation, local equilibria (LE) based thermodynamic and kinetic framework has been adopted to comprehend eutectoid transformation mechanism in Fe–C–Cr systems utilizing unified interaction parameter formalism (UIPF). For theoretical estimations using UIPF, all the necessary thermodynamic parameters have been evaluated. It has been demonstrated that UIPF is an efficient tool for predicting metastable phase boundaries in wide ranges of temperature and composition, where majority of commercial thermodynamic simulation packages have prediction limitation. Growth rates and interlamellar spacings during pearlite formation in various Fe–C–Cr systems predicted by UIPF-based LE models have been compared with experimental data reported previously. The reasonably good agreement between theoretical predictions and experimental data not only affirms the potential of adopted models in predicting eutectoid transformation mechanisms in Fe–C–Cr systems, but also helps in addressing some of the long-standing ambiguities pertaining to pearlite formation mechanism in the considered alloys.
