The lattice parameters of any homogeneous ternary solid solution section in the Cr-W-Mo system were obtained from experimental curves. A diagram of composition versus lattice parameter for three sectional cuts were plotted on the basis of changes in lattice parameter of phases present in the alloys at 1600, 1300, and 1000 deg C. The first group of vertical cuts was determined for a constant amount of 10, 20, and 30% Mo in the alloy. The other two groups of cuts were taken for a constant content of 20, 20, and 50% Cr in the alloy, and for a constant content of 40, 50, and 60% W in the alloy. The direction of the conical section in the twophase region ( alpha /sub 1/ + alpha /sub 2/ solid solutions) for the separation of a ternary solid solution were determined for isothermal sections at 1100 and 1300 deg C. It is shown that there is a ternary critical point due to instability of the ternary solid solution above the critical temperature in the chromiumtungsten system. The spatial diagram is asymmetric in form due to a shift toward the high-melting metals of tungsten and molybdenum. (TTT)
