The system Fe–Ni–Cr: revision of the thermodynamic description

Phase equilibria of the Fe–Cr–Ni ternary systems and interfacial reactions in Fe–Cr alloys with Ni substrate

“…5 shows the isothermal section of the Fe-Cr-Ni ternary system at 750 • C and it is constructed based on experimental results and the phase diagrams of three constituent binary systems. There are two tie tri-angles, ␥ + ␣ + and ␥ + ␣ + , in this Fe-Cr-Ni isothermal section at 750 • C. The experimental observations show satisfactory agreement with calculated results [17,23,24]. This result is also similar to the isothermal section of the Fe-Cr-Ni ternary system at 800 • C from literature [9].…”

“…10. In comparison with the isothermal section at 900 • C [9], the phase range of the phase at 850 • C is smaller than it at 900 • C. The experimental results are still similar to the calculated results [17,23,24].…”

“…Both of the Cr-Ni [13,14] and Fe-Ni [15] binary system have been completely studied and published. A considerable amount of reports have investigated the phase equilibria of the Fe-Cr-Ni ternary system at various temperatures [9,[16][17][18][19][20][21][22][23][24]. The ternary intermetallic compound, phase, is formed over 900 • C [9].…”

“…The ternary intermetallic compound, phase, is formed over 900 • C [9]. However, the relevant literature has seldom reported the phase equilibria of the Fe-Cr-Ni ternary system at 750 or 850 • C and the phase equilibria information is not complete [17,20,23,24]. Only a little research regarding the interfacial reactions on Fe-Cr/Ni couples can be found [25,26].…”

Ternary thermodynamics by computer-aided Knudsen cell mass spectrometry: Bcc solid ternary Fe–Co–Cr alloys

“…(6) and (7) yields the required best-fit formula. For bcc solid Fe-Co-Cr alloys all three binary boundary systems are well-established in literature: The Co-Cr [8] and Cr-Fe [9] bcc solid alloys have been determined massspectrometrically, and the resultant molar excess Gibbs energies have been used successfully for calculations of the binary phase diagrams [8][9][10]. The TAP parameters of bcc solid Fe-Co alloys have been assessed by means of phase boundary calculations based upon experimental data of the fcc and liquid phases [11].…”
