39 nickel copper phase diagram
The phase diagram of the barium sulfide-copper(I) sulfide system was investigated above 873 K (600 °C) using a custom-built differential thermal analysis (DTA) apparatus. The melting point of barium sulfide was determined utilizing a floating zone furnace. ... Reduction roasting of copper, nickel, and iron sulfides in conventional and plasma ... Atomic percent nickel Phase diagram for Gold-Nickel showing complete solid solubility above about 800oC and below about 950oC. The miscibility gap at low temperatures can be understood with a regular solution model.

The abscissa ranges from 0 wt% Ni (100 wt% Cu) to 100 wt% Ni (0 wt% Cu). Three different phase regions (or fields) appear in the diagram: anα field, a liquid (L) field, and a two-phase α+ L field. The liquid L is a homogeneous liqu...
