ABSTRACT. The thermodynamic quantities such as the mean nearest neighbor distance, the free energy, the isothermal and adiabatic compressibilities, the isothermal and adiabatic elastic modulus,the thermal expansion coefficient, the heat capacities at constant volume and at constant pressure, the entropy of interstitial double alloywith bcc structure with the concentration of interstitial atoms is very small are derived by the statistical moment method. The obtained expressions of these quantities depend on temperature and concentration of interstitial atoms. The theoretical results are applied to interstitial alloys FeX (X = Si, Li, H)and the numerical results are compared with the experimental data.
