ficient, entropy, helmholtz free energy, heat capacity at constant pressure and heat capacity at constant volume were calculated. The results show the calculated linear thermal expansion coefficient, entropy, helmholtz free energy, heat capacity at constant pressure and heat capacity at constant volume with taking into account the electronic contribution are in good agreement with experimental measurements for temperatures up to 2000 K. On the basis of the above results, elastic properties of cubic tungsten are obtained. The temperature dependences of elastic coefficient, bulk modulus, shear modulus and young's modulus are also got, which are in good agreement with experimental data
