Study on Thermodynamic and Elastic Properties of B₂-FeSi by Statistical Moment Method
Nguyen Quang Hoc and Nguyen Duc Hien

The thermodynamic and elastic theory of B₂ substitutional alloy AB and B₂ interstitial alloy AB under temperature and pressure are derived by the statistical moment method. In the case of zero concentration of substitutional atoms B and interstitial atoms B, we obtain the thermodynamic and elastic theory of main metal A with simple cubic structure. Our numerical calculations according to the model of interstitial alloy for B₂-Fe₉₉Si₁ and the model of substitutional alloy for B₂-Fe₅₀Si₅₀ in the temperature interval from zero to 1500K and the pressure interval from zero to 160 GPa are in relatively good with experiments and other calculations

Keywords: B₂ structure, interstitial and substitutional alloy, thermodynamic and elastic quantities, statistical moment method
