Thermodynamic Analysis of Fe-Ti-C System

Abstract

Abstract: The thermodynamics of Fe-Ti-C system was calculated by the calculation of phase diagram (CALPHAD) method to
investigate the influences of Fe content and C/Ti atomic ratio on the adiabatic temperature (T_ad) and equilibrium phases. It is
revealed that Fe content has more effects on the adiabatic temperature than on equilibrium phases. The desired equilibrium phases (TiC+Fe)
can be obtained no matter how Fe content value varies when C/Ti (atomic ratio) is fixed as about 1.0. The combustion synthesis reaction
of Fe-Ti-C system can be ignited thermodynamically with Fe weight content up to 55%. C/Ti atomic ratio has more effects on the equilibrium phases
than on adiabatic temperature. The temperature of graphite appearing decreases when C/Ti (atomic ratio) reduces. And the graphite content
varies from about 1% to 16% when C/Ti (atomic ratio) varies from 1.0 to 1.4 at low combustion temperature.
