  A method to measure thermophysical characteristics (TPC) of conductive
materials is described. The method is based upon controlled bulk (e.g., Ohmic)
heating and measurement of the averaged over the volume of a sample temperature
and the temperature of the surface of a sample. To measure averaged over a
sample volume temperature a dilatometric technique could be used and surface
temperature could be measured by x-ray method. This allows one to avoid
distortion of the temperature field by the thermocouples and directly takes
into account heat losses from the surface of a sample. The treatment of the
experimental data should be based upon theoretical calculations presented in
this paper. The measured values of the averaged over the volume of a sample
temperature and a surface temperature allow for the calculation of TPC of the
material. The experimental data obtained on the iron-based materials prove the
high accuracy of the described approach [1-3].
