Deoxidation Equilibrium of Aluminum and Silicon in the Liquid Iron-Nickel Alloys

Thermodynamics of Oxygen Solutions in Carbon-Containing Fe-Ni Alloys

“…1. These data show that, as the nickel content of the melt increases, the equilibrium constant of reaction (5), like that of reaction (1), decreases significantly, which can also be explained by a considerable weakening of oxygen and carbon bonds in the melt as the nickel content increases.…”

“…Inasmuch as the quantity [%O] is small, we may assume that ≈ . This substitution does not introduce a noticeable error in the calculations [4,5]. Then,…”

“…The concentration of oxygen in equilibrium with a specified carbon content for reaction (5) can be calculated by the equation…”

“…For silicon, The calculated equilibrium constants for reaction (1) at different nickel contents of the melt at 1873 K are presented in Table 1 and Fig. 1 in comparison with the data on oxygen solutions in Fe-Ni melts containing Mn [1,4], Cr [2], V [2], Si [1,4], Ti [2], and Al [2,5].…”

“…The thermodynamics of oxygen solutions in Fe-Ni melts containing Mn, Si, Al, Cr, V, and Ti has been studied in sufficient detail [1][2][3][4][5]. However, no information is available on oxygen solubility in carbon-containing Fe-Ni melts.…”
