Study of the Liquidus and Solidus Surfaces in the Quaternary Fe–Ni–Cu–S System: III. Construction of a Meltability Diagram and Determination of Miscibility Gap Boundaries for the Ternary Cu–Ni–S Sulfide System

摘要

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 misci- bility gap region of this system are determined. A solidus surface is plotted for the Cu–Ni–S system for the first time.
