[en] The thermal spike model in materials under the irradiation by swift heavy ions with high specific energy loss is considered taking into account the temperature dependence along the ion trajectory. The numerical solutions of the temperature system equations for the temperatures of lattice up to the melting and evaporation points, i.e., with the two phase transitions are obtained. The pressure in the volume of heavy ion track and its influence on the changes of thermodynamical parameters are introduced. The influence of defects on the 'hot' electron free path is discussed. The numerical analysis of the lattice temperature at low and high temperatures of the thermal conductivity and heat capacity parameter values was carried out. (author)
