Аннотация:We present a modification of the semiempirical description of the volume–temperature dependences of the electrical and thermal conductivities of α iron that has a body-centered cubic lattice. We consider an interpolation of the volume–temperature dependences of the resistivity and thermal conductivity of α iron along high-temperature isobars and high-pressure isotherms in the pressure range from –5 to +5 GPa at temperatures of 400–800 K, which correspond to the thermodynamic conditions of the standard and emergency functioning of iron alloys. The interpolation of the electrical and thermophysical properties of α iron is performed based on the developed equation of state of α iron at high pressures and high temperatures. The effect of compression and extension on the thermal conductivity of α iron is estimated.
