A Knudsen effusion technique combined with mass-spectrometric analysis of the evaporated products has been used to investigate the gaseous phase and to determine the thermodynamic properties of {xFe +yMn + (1−x−y)Si}(1) in the temperature range 1435 K to 1823 K and of {xFe +yMn + (1−x−y)P}(1) in the temperature range 1302 K to 1701 K. Concentrations of the components varied within the mole-fraction rangesx, 0 to 1;y, 0 to 0.6; and (1−x−y), 0 to 1 in the first system, andx, 0.205 to 0.738;y, 0.22 to 0.695; and (1−x−y), 0.152 to 0.365 in the second. The isoactivity lines of silicon and phosphorus are close to the secants connecting the Fe-Si and Mn-Si, Fe-P and Mn-P binary sides. Iron and manganese activities decrease regularly as the configuration point runs from {xFe+(1−x)Mn}(1), towards {xFe + (1−x)Si}(1) or {yMn+(1−y)Si}(1), and towards {xFe+(1−x)P}(1) or {yMn+(1−y)P}(1). The thermodynamic properties have been described with the associated-solution model assuming that binary and ternary complexes exist in the melt.
