By utilizing the tools of the PyCALPHAD library and a thermodynamic database, Python-based software components were developed to calculate the energetic characteristics of phase transitions, enabling the prediction of Fe–W–C system behavior under varying composition and temperature. According to the CALPHAD calculation, it was established that within the temperature range of 500–2000 K for the composition of 43 at.% Fe, 43 at.% W, and 14 at.% C, an intermediate Fe3W3C phase is formed, which melts incongruently at 1770K.
