“…Thermodynamic calculation in the frameworks of the CALPHAD (CALculation of PHAse Diagrams) approach allows to spare time and efforts required to design new materials [15][16][17]. The Fe-Nb-Si system has been experimentally investigated for several times [18][19][20][21][22][23][24][25][26][27][28][29][30]. The obtained experimental data are used as the basis of thermodynamic calculations.…”

Nb-Si based alloys have drawn continuously increasing attention due to their excellent high-temperature mechanical properties. The addition of element Fe could improve their poor high-temperature oxidation resistance which largely restricts their applications. With the aim to study the effect of Fe addition on the Nb-Si system and to design appropriate alloy composition, the Fe-Nb-Si ternary system has been thermodynamically investigated using the CALPHAD (CALculation of PHAse Diagrams) approach aided with the formation enthalpies for ternary compounds at 0 K computed via ab initio calculations. A self-consistent thermodynamic description of the Fe-Nb-Si system was obtained in this work. Key isothermal sections and liquidus projection were presented, and the calculation results show a good agreement with available experimental data.
