Abstract
The volumetric properties of liquid indium-lead alloys containing 20 and 33 at. % Pb have been measured using gamma-ray attenuation technique at temperatures from the liquidus line to 880 K. The density changes of these alloys during solid-liquid phase transition have been calculated. The obtained experimental values of the molar volume and the volume thermal expansion coefficient of melts and the results of calculations according to the laws for an ideal solution and data of other authors have been compared.
