Abstract
Magnesium activities in liquid magnesium-lead alloys have been measured with electromotive force cells over the temperature range 745 to 868 K and over the mole fraction range 0.03 <X Mg<0.50. The exper imental data were used to evaluate the parameters in the empirical temperature-composition relationship proposed by Krupkowski for describing the activity coefficients. Values generated from the Krupkowski formulae were utilized with data for liquidus compositions to evaluate the free energies of formation of the solid intermediate phases and compared with available experimental data for Mg2Pb.
