3D Computer Model of the Ni–Cu–NiS–Cu2S Subsystem Txy Diagram above 575°C

  • 13 Accesses

Abstract

The three-dimensional computer model of the Ni–Cu–NiS–Cu2S subsystem T–x–y diagram above the ternary eutectic temperature 575°C is represented. It is shown that in the ternary system with Ni the liquid immiscibility in the subsystem Cu–Cu2S is transformed into the small region of immiscibility within the Cu2S liquidus field.
