• Determination of activity coefficients of liquid Co-Cr, Co-Ni, and Cr-Ni alloy systems was carried out by means of high temperature Knudsen cell mass spectrometry. Measurements of ion intensities of components of alloys were made within liquid phase compositions at temperatures ranging from 1,723 to 1,873 K. The behavior of the ratio of the activity coefficients with composition derived from ion intensity measurements for all the alloys studied indicates that activity coefficients of these alloys obey the quadratic formalism. Activity coefficients are given in the form of quadratic formalism. In particular, liquid Co-Ni alloy behaves as the regular solution with slightly positive enthalpy of mixing.
