Abstract
Ortho-equilibrium (OE) and para-equilibrium (PE) thermodynamic calculations were carried out to predict the phase boundary for hypo- and hyper-eutectoid low alloy steels. The temperature variation of the partitioning effect of substitutional alloying elements on the actual phase boundary was considered. A new temperature formula was proposed as a function of chemical composition based on the thermodynamic calculations, which could predict the accurate phase boundary of various low alloy steels not only in the high temperature hyper-eutectoid region, but also in the low temperature hypo-eutectoid region. It is anticipated that the proposed formula can be useful for the calculation of various phase transformations of multi-component austenite with wide ranges of temperature and composition.
