Abstract

Abstract—The “cooling” method based on the Newton–Richmann law is used to measure specific heat capacity. It is shown that, as the manganese concentration in aluminum—magnesium alloys and temperature increase, the specific heat capacity of the alloys increases; as the scandium concentration increases, the heat capacity slightly decreases. As the temperature increases, the specific enthalpy and entropy of the alloys increase, whereas the specific Gibbs energy decreases. Scandium additions almost do not affect changes in thermodynamic functions of the alloys.
