Abstract
The Knudsen effusion method was used for measurements of mass loss rate of dilute solutions of lead and iron in liquid copper. The results were used t o calculate the first order ternary interaction parameter epsilon(Pb)(Fe). A value of epsilon(Pb)(Fe) = -1.970 was obtained in the temperature range ( 1373 K < 7 < 1687 K. The isoactivity curves of the components of the ternary system were calcula ted and the lines of constant molar enthalpy of mixing in the liquid phase were plotted, as well as the position of the liquidus surface. The results were compared with literature data.
