Объемно-температурная Зависимость Электро- И Теплофизических Свойств Alpha-Железа При Высоких Давлениях И Температурах

Modification of the semiempirical description of the volume-temperature dependence of the electrical conductivity and thermal conductivity of alpha-iron (iron having a body-centered cubic lattice structure) is presented. The interpolation of the volume-temperature dependences of the resistivity and thermal conductivity of alpha-iron along high-temperature isobars and high-pressure isotherms in the pressure range from -5 GPa to +5 GPa and temperatures of 400-800 K is considered for the conditions of normal and emergency operation of iron alloys. The interpolation of the electro-and thermophysical properties of alpha-iron is performed on the basis of the developed equation of state of alpha-iron at high pressures and temperatures. the effect of compression and tensile pressure on the thermal conductivity of alpha-iron is estimated.
