The specific heat capacity, heat-transfer coefficient and thermodynamic functions of the AlV0.1 aluminum conductor alloy with sodium were determined in the cooling mode using the known specific heat capacity of a reference aluminum sample (grade A5N). To this end, polynomial fits describing the cooling rates were obtained by processing the cooling-rate curves of the AlV0.1 alloy samples with sodium and of the reference. Using the cooling-rate values of the tested alloy samples and of the reference, together with their masses, the specific heat capacity and thermodynamic functions of the AlV0.1 aluminum conductor alloy with sodium were calculated as functions of temperature. It was shown that with increasing temperature and sodium content the heat capacity, enthalpy and entropy of the AlV0.1 aluminum alloy increase slightly, while the Gibbs free energy decreases.
