“…So far, the Fe-P [13][14][15][16][17][18][19] and Fe-Si [20][21][22][23][24][25][26][27] systems have been thermodynamically modeled in many studies and were recently reoptimized by the present authors [28,29]. A complete thermodynamic modeling of the Si-P system was performed by Jung and Zhang [30] and Liang and Schmid-Fetzer [31].…”

“…The aim of this work is to conduct a critical thermodynamic re-optimization of the Si-P and Si-Fe-P systems to develop a more accurate and reliable thermodynamic database, which is of great importance for materials engineering embracing such alloy systems. The recently optimized Fe-P [28] and Fe-Si [29] systems by the present authors were adopted in this study. The phase equilibria and thermodynamic properties of the Si-P and Si-Fe-P systems were determined based on reliable experimental data.…”

Thermodynamic modeling of the Si–P and Si–Fe–P systems was performed using the CALculation of PHAse Diagram (CALPHAD) method based on critical evaluation of available experimental data in the literature. The liquid and solid solutions were described using the Modified Quasichemical Model accounting for the short-range ordering and Compound Energy Formalism considering the crystallographic structure, respectively. In the present study, the phase boundaries for the liquidus and solid Si phases of the Si–P system were reoptimized. Furthermore, the Gibbs energies of the liquid solution, (Fe)3(P,Si)1, (Fe)2(P,Si)1, and (Fe)1(P,Si)1 solid solutions and FeSi4P4 compound were carefully determined to resolve the discrepancies in previously assessed vertical sections, isothermal sections of phase diagrams, and liquid surface projection of the Si–Fe–P system. These thermodynamic data are of great necessity for a sound description of the entire Si–Fe–P system. The optimized model parameters from the present study can be used to predict any unexplored phase diagrams and thermodynamic properties within the Si–Fe–P alloys.
