Summary:The paper demonstrates the applicability of the model of a two-phase locally equilibrium region for calculating temperature dependences of heat capacity, linear thermal expansion coefficient, and thermal diffusivity of various metals. It is shown that the proposed correlations allow describing the enhancement of thermal characteristics with increasing temperature and associated changes during phase transition. The established correlations can be extrapolated to experimentally unexplored domains. The relative simplicity of the model in establishing relations, universality in when describing various types of solids, and clear theoretical results make this model suitable for use in engineering and technical calculations.
