“…Although the motion of the liquid-Cu/cFe interface is a balance between two independent processes-the removal of Fe because of oxidation and the back-diffusion of Ni and Cu-it was assumed that the development of interface morphology results mainly from the back-diffusion process. Besides super-saturation, internal oxides [11] and changes in surface tension [37,38] caused by Ni also could affect the interface roughness. However, as will be shown later in Figure 6, the interface becomes uneven and few internal oxides are present.…”

Steel produced in an electric arc furnace (EAF) contains a high amount of Cu that causes a surface-cracking phenomenon called surface hot shortness. Ni reduces the risk for surface hot shortness, and this work focuses on investigating the following two phenomena caused by Ni during oxidation at 1150°C for Fe-Cu-Ni alloys: (1) the decrease in oxidation rate and (2) the formation of a wavy liquid-Cu/oxide and of liquid-Cu/c-iron (cFe) interfaces, which promote Cu occlusion into the scale. Thermogravimetry, scanning electron microscopy, and transmission electron microscopy-energy dispersive spectroscopy techniques were applied. A numerical model also was developed to explain the experimental results. High Ni contents cause higher liquid-Cu/cFe interface nickel concentrations and more potential for an interface breakdown. The decrease in oxidation rate by adding nickel can be explained qualitatively by the decrease in Fe cation transport through the wu¨stite layer.

“…However, as will be shown later in Figure 6, the interface becomes uneven and few internal oxides are present. The change in surface tension caused by Ni could be a possibility, but the data available for the Fe-Cu-Ni system [38] are at significantly higher temperatures. More work is needed to explore this possibility.…”

The density and surface tension of Cu-Co-Fe alloys have been measured using the non-contact technique of electromagnetic levitation. At temperatures above and below the liquidus point, the density and surface tension are linear functions of temperature. The experimental density results can be predicted by means of the regular solution model from the binary phases alone, i.e., no assumption about ternary interactions needs to be made. The surface tension values are in good agreement with numerical solutions of the Butler equation if the known Gibbs excess energies are used. It is found that, for Cu-Co-Fe, it is possible to predict the surface tension from the binary systems as well. In addition to this, the surface tension is insensitive to substitution of the two transition metals, Co and Fe.

For the liquid Fe-Cu-Mo ternary system, the surface tensions of three selected alloys, i.e., three typical monotectic alloys, were measured by the electromagnetic levitation oscillating drop method over a broad temperature range, including both superheated and undercooled states. The maximum undercooling attained is up to 173 K. The experimental results show a good linear correlation between the surface tension and the temperature. By applying on the Butler equation, the surface tensions were also calculated and they are in good agreement with the measured ones, except that in the undercooled state, the calculated value is slightly larger than the measured results. Interestingly, both the measured and calculated results indicate that the enriched element on the droplet surface is much more conspicuous than other elements in influencing the surface tension. Besides, the viscosity and the density of the liquid Fe-Cu-Mo ternary alloys are also derived on the grounds of the experimentally measured surface tensions.
