A study of the iron-chromium-nickel ternary system

Application of dual-anneal diffusion multiples to the effective study of phase diagrams and phase transformations in the Fe–Cr–Ni system

“…There is overall agreement on the general topology of the phase diagram, but some differences can be noted. For instance, the Cr solubility in the c phase obtained from the current study is about 2-3 at.% higher than most data reported by prior studies, except those reported by Pugh and Nisbet [22], which are quite different from all other data sets.…”

“…12. The 800°C Fe-Cr-Ni isothermal section (at.%) determined from this study in comparison with the Thermo-Calc calculation result as well as prior experimental results reported in the literature [8,12,13,22].…”

Formation of a blocky ferrite in Fe–Cr–Ni alloy during directional solidification

“…This solid-state transformation is a result of the nature of the d and g solvus, as can be seen from the constant Fe vertical section of Fe-Cr-Ni phase diagram, as shown in Fig. 1 [16]. From the path on the vertical section of Fe-Cr-Ni phase diagram at 70 wt% Fe, it is known that solid-state transformation from ferrite to austenite will occur first on cooling after solidification in 18-8 austenitic stainless steel.…”

Residual Thermal Phase Stresses in α-γ Fe-Cr-Ni Alloys Measured by a Neutron Diffraction Time-of-Flight Method

“…2,3) Harjo et al measured σ ph th in α-γ Fe-Cr-Ni alloys firstly by using a neutron diffractometer with an angle-dispersion (AD) method at Research Reactor Institute of Kyoto University (KURRI). 3) In their study, five Fe-Cr-Ni alloys were prepared, whose chemical compositions lie on an equilibrium tieline in the ternary phase diagram; 4) an α single phase (S5), a γ single phase (S1) and three α-γ dual phase (S2, S3 and S4) alloys. The σ ph th produced by rapid quenching after solution treatment in the dual phase alloys were determined where the α and γ single phase alloys were used as the relevant reference materials.…”
