Thermal properties of liquid alloys of magnesium-lead system

The temperature variations of the density of liquid magnesium-lead alloys were measured by the gamma-method in the temperature range from the liquidus temperature to 950–1000 K for compositions of 19.11, 33.45, 52.46, and 83.06 at. % Pb. It is shown that within the estimated errors (0.25–0.30 %), the alloy density depends linearly on the temperature. Approximation dependences ρ(T) were obtained for every studied composition together with generalizing density-temperature and density-concentration dependences for the range of 0–100 at. % Pb. The work was financially supported by the Russian Foundation for Basic Research (Grant No. 06-08-00040).
