Phase Relationship in the Zr-Mo-Fe(O) System (Zr > 30 at.%) at 1000 °C
The impact of oxygen impurity on phase relationships in the Zr-Mo-Fe system (Zr > 30 at.%) at 1000 °C was investigated by means of x-ray diffraction, scanning electron microscopy, and energy-dispersive spectroscopy analysis. An oxygen-stabilized ternary compound γ-Zr2(Mo,Fe), derived from Ti2Ni type Zr4Fe2O, with cell parameter of a = 1.2213 nm was observed to be present in the investigated Zr-Mo-Fe alloys. The phase relationships of the Zr-Mo-Fe (O) system at 1000 °C in the Zr-rich corner consist of 3 four-phase regions, i.e., [βZr + λ-Zr(Mo,Fe)2 + γ-Zr2(Mo,Fe) + ZrMo2], [βZr + λ-Zr(Mo,Fe)2 + γ-Zr2(Mo,Fe) + Liquid], and [λ-Zr(Mo,Fe)2 + γ-Zr2(Mo,Fe) + Liquid + ZrFe2]. The previously detected Zr9Mo4Fe compound was not observed in this work.
期刊介绍：
The most trusted journal for phase equilibria and thermodynamic research, ASM International''s Journal of Phase Equilibria and Diffusion features critical phase diagram evaluations on scientifically and industrially important alloy systems, authored by international experts.
The Journal of Phase Equilibria and Diffusion is critically reviewed and contains basic and applied research results, a survey of current literature and other pertinent articles. The journal covers the significance of diagrams as well as new research techniques, equipment, data evaluation, nomenclature, presentation and other aspects of phase diagram preparation and use.
Content includes information on phenomena such as kinetic control of equilibrium, coherency effects, impurity effects, and thermodynamic and crystallographic characteristics. The journal updates systems previously published in the Bulletin of Alloy Phase Diagrams as new data are discovered.
