Abstract

In this study, the Statistical Moment Method (SMM) is applied to investigate the structural properties of the W-Fe alloy at temperatures up to 3000 K and pressures up to 20 GPa. Analytical expressions for the free energy are derived, along with explicit formulas for structural quantities such as lattice constants and volume, taking into account the effects of anharmonicity. The results obtained from the SMM show good agreement with existing theoretical calculations and experimental data. This method demonstrates strong potential for further extension to the study of elastic properties, thermodynamic quantities, and the melting temperature of the W–Fe alloy in future work.
