Аннотация
The enthalpy of solid and liquid Rb73Bi27 alloy is measured via massive isothermal drop calorimeter in the temperature range 430–1225 K. Approximating equations are determined. The isobaric heat capacity and enthalpy change on melting and the solid state transformation are determined. The estimated errors for enthalpy and heat capacity are 0.5 and 1.5%, respectively. It is found that the heat capacity of the liquid alloy falls upon heating above the liquidus. Tables of the recommended values of caloric properties in the range of 298.15 to 1225 K are developed. It is shown that the caloric properties of alloys differ considerably from calculations performed using the laws for ideal solutions.
