“…The practical and theoretical importance of Cu-Fe-Co alloys has promoted a number of thermodynamic assessments of the system [8,[14][15][16][17]. Note that these papers contain inaccuracies that are mainly related to the description of liquidus temperatures and metastable liquid phase separation temperatures.…”

The mixing enthalpies of ternary Cu-Fe-Co liquid alloys are studied by the calorimetric method at 1873 K and x Co = 0-0.55. Thermodynamic assessments of the Fe-Co and Cu-Fe-Co systems are carried out with the CALPHAD method. A set of self-consistent thermodynamic parameters of the phases is obtained using data on the mixing enthalpies established in this study and published information on phase transformations. Isothermal and vertical sections of the phase diagram, liquidus and solidus surfaces, and metastable miscibility gap for overcooled liquid alloys are calculated. The undercooling degrees for the metastable liquid phase separation and temperaturecomposition ranges of the formation of the supersaturated solid solutions during the liquid quenching have been assessed.

“…The difficulty with mass producing catalytic metals and alloys is that the final powder product should be nanoscale, and many of the alloys are highly immiscible (e.g., Co-Cu [31] and Fe-Cu [32]), so processing cannot be done via traditional methods.…”

Carbon nanofibers were generated over bimetallic catalysts in an atmospheric pressure chemical vapor deposition (APCVD) reactor. Catalyst compositions of Fe 30 at%, Cu and Ni 30 at% and Cu were mechanically alloyed using high-energy ball milling over durations of 4,8,12,16, and 20 h. The catalyst powders were then used to produce carbon nanofibers in ethylene and hydrogen (4:1) at temperatures of 500, 550, and 600 °C. The microstructures of the catalysts were characterized as a function of milling time as well as at deposition temperature. The corresponding carbon deposition rates were assessed and are correlated to the microstructural features of each catalyst. The milling process directly determines the performance of each catalyst toward carbon deposition, and both catalysts performed comparably to those made by traditional co-precipitation methods. Considerations in miscible and immiscible nanostructured alloy systems are discussed.
