This work is a continuation of the cycle of studies dealing with the phase transformations occurring in the ternary systems bounding the quaternary Fe-Ni-Cu-S system. A meltability diagram is plotted for the ternary Cu-Ni-S sulfide system using differential thermal analysis, scanning electron microscopy, and electron-probe microanalysis, and miscibility gap boundaries and the positions of conodes in the miscibility gap region of this system are determined. A solidus surface is plotted for the Cu-Ni-S system for the first time.
