“…The recent thermodynamic assessment of the Cu-Fe-Ni system has been carried out by several groups of authors. [12,44,45] Servant et al [12] assessed the Cu-Fe-Ni system taking into account the disorder/order transformation between fcc-Al and (Cu,Ni) 3 Fe base on the new experimental data. Turchanin et al [44] improved the description of the miscibility gap and phase equilibria involving liquid phase.…”

“…But the order/disorder phase transformations have not been considered. Dreval et al [45] updated the thermodynamic description of the Cu-Fe-Ni system considering the newly available experimental data based on the work of Turchanin et al [44] The thermodynamic parameters of the Cu-Fe and Cu-Ni subsystems adopted in the work of Dreval et al [45] were inconsistent with the ones accepted in our established Al-base thermodynamic database. Hence, the thermodynamic parameters of the Cu-Fe-Ni system assessed by Servant et al [12] were adopted in our thermodynamic database.…”

Based on the critical review of the available experimental phase equilibrium data for the constituent quaternary systems in the Al-Fe-Mg-Ni-Si and Al-Cu-Fe-Mg-Ni quinary systems, a set of self-consistent thermodynamic parameters for these systems has been obtained using the CALPHAD approach. In combination with the constituent binary, ternary and quaternary systems, the thermodynamic database for the quinary Al-Fe-Mg-Ni-Si and Al-Cu-Fe-Mg-Ni systems was developed. Comprehensive comparisons between the calculated and measured phase diagrams and invariant reactions showed that the experimental data were satisfactorily accounted for by the present thermodynamic description. The established database was used to describe the solidification behaviors of Al alloys 6063 (Al-0.39Si-0.20Fe-0.43Mg, in wt.%) and 2618 (Al-2.24Cu-1.42Mg-0.9Fe-0.9Ni, in wt.%) under Gulliver-Scheil non-equilibrium condition. The reliability of the present thermodynamic database was also verified by the good agreement between the Gulliver-Scheil calculation and experiment.

“…In addition to this phenomenon, quenching of the molten Cu-Fe-Ni alloy into a single homogeneous phase was found to be very challenging. The solidifying Cu-Fe-Ni alloy often segregated into a Cu-rich phase and Fe-Ni rich phase in quenching, resembling the presence of miscibility gap in the copper-iron binary system [11] and its extension to the ternary alloys. It is possible that the presence of trace elements, such as lead and possibly silver, enhances this behavior [11].…”

To capture efficiently the valuable trace metals from nickel slag using electric furnace, it is important to study their distributions between the slag and metallic phases in the furnace. It is impossible to calculate accurately these distributions without experimental measurements. Therefore, in this work, selected trace metal distributions and phase equilibria between K2O containing iron-silicate slags and a metallic Ni-Fe-Cu alloy in nickel slag cleaning furnace conditions were studied. The experimental method developed and applied during the work, involved a modified quenching technique that included equilibration of the samples in semi-sealed quartz ampoules in an inert atmosphere and metallic Fe saturation. The use of the semi-sealed quartz ampoule prevents the escape of volatile elements from the sample during equilibration. Chemical compositions of the phases and the trace elements were analysed by EPMA. From the measured compositions, the trace metal distribution coefficients between the molten Ni-Fe-Cu alloy and slag were calculated.
