The liquidus and solidus temperatures of FeCrAl stainless steel were determined by differential scanning calorimetry (DSC) at different heating rates. They were also calculated by Thermo-calc software and empirical formulae separately. The accuracy of calculation results was assessed by comparison with the corresponding DSC results. The liquidus temperatures calculated by empirical formulae, which exhibited a maximum deviation of 8.6℃, were more accurate than those calculated using Thermo-calc, which exhibited a maximum deviation of 12.11℃. On the basis of Thermo-calc calculations performed under the Scheil model, the solidus temperature could be well determined from solid fraction (fS) vs. temperature (t) curves at fS = 0.99. Furthermore, a theoretical analysis to determine the solidus temperature with this method was also provided.
