In addition to these, Wang et al. found a new ternary phase τ9 (Zr 29 Fe 29 Si 42) through detailed experiments , and Gabay et al. recently found a metastable hard magnetic phase ZrFe 10 Si 2 with a ThM 12 structure , . We refer to the latter phase as τ10 in this paper for convenience. Aluminum and iron form the equilibrium Al 13 Fe 4 phase, but non-equilibrium solidification of alloys containing iron as an alloying element or impurity can lead to the formation of various metastable intermetallic phases, such as Al 6 Fe, Al m Fe or Al x Fe [10,11,12]. The competition between superconductivity (SC) and Fe-AFM in the charge-lightly doping region has been widely revealed 4,5,6,7,8, however, the systems with unusual phase diagrams are also worth ...

Interestingly, on the R-Fe (R = rare earth) binary phase diagram 26 (see Supplementary Fig. 1), Fe forms a eutectic system with R 2 Fe 17 —a typical negative thermal expansion (NTE ... Figure 1 shows the calculated phase diagrams of the Fe-Mn and Fe-Ti systems using the model parameters optimized by Huang and Wang et al. , as well as the experimental data [18, 27,28,29,30,31,32,33,34,35,36,37,38,39]. The experimental phase equilibria in the two binary systems are satisfactorily reproduced. The solidification of AlCuSi alloys with Mn and Fe was studied by rotating a magnetic field to understand the effect of melt flow. The specimens solidified with a forced convection, low cooling rate and low temperature gradient. Electromagnetic stirring generated by an electric coil around the specimens caused a transformation from equiaxed dendritic to rosette morphology, occasionally with ... The CaO·3(Al,Fe) 2 O 3, (C(A,F) 3), phase forms a solid solution in the FeO-Fe 2 O 3-CaO-Al 2 O 3 system and is an end member of the SFCA (Silico-Ferrite of Calcium and Aluminum) suite of solid solutions observed in industrial iron ore sinters. SFCA acts as a bonding phase in these sinter materials so an accurate description of the phase equilibria and thermodynamic properties of this phase ...

In addition, the investigations on the ternary phase diagram of Y-Fe-B indicate that there is no impurity phase like soft magnetic REFe 2 apart from Y 2 Fe 14 B within the variation of the stoichiometric . On one hand, this can simplify the phase transformation process of NdY-Fe-B so that a high purity 2:14:1 phase will be obtained.

Face centered cubic (FCC) high-entropy alloys (HEA) exhibit excellent ductility while body centered cubic (BCC) HEAs are characterized by high strength. Development of fine two-phase eutectic microstructure (consisting of a tough phase such as fcc and a hard phase such as bcc/intermetallic) can help in obtaining an extraordinary combination of strength and ductility in HEAs. Designing eutectic ...

The tolerance of Fe in cast alloys is strongly related to the Al 8 Mn 5 phase, which is a complex intermetallic phase dissolving Fe on the same sublattice jointly with Mn, modeled as (Al) 12 (Mn) 5 (Al,Mn,Fe) 9. The phase diagram calculations near the solidus temperature of the AM and AZ alloys reveal that a key phase boundary can be identified ...

Iron (/ ˈ aɪ ər n /) is a chemical element with symbol Fe (from Latin: ferrum) and atomic number 26. It is a metal that belongs to the first transition series and group 8 of the periodic table.It is, by mass, the most common element on Earth, right in front of oxygen (32.1% and 30.1%, respectively), forming much of Earth's outer and inner core.It is the fourth most common element in the ...

The magnetic properties show that the Ba 0.2 Sr 1.8 Co 2 (Fe 0.96 Al 0.04) 12 O 22 crystal has the highest ordering temperature and largest volume fraction of the ALC phase at zero H; further, after the application of an in-plane H, it exhibits a maximized volume fraction of the metastable TC phase, resulting in the highest ME susceptibility ...

The short rod-like Fe phase is α-Al 8 Fe 2 Si, this phase exists in the alloy containing V, the amount of it increases with the increase of V content. According to the results of XRD, the Al 15 (Fe, V) 3 Si 2 phase described in some papers has not been detected in this experiment.

Meanwhile Moura et al. pointed out that the selective dissolution of Fe and formation of Cr oxide layer led to the Cr enrichment in the passive film, and the high fraction of grain boundaries accelerated the above process. In this study, the grain size of the SZ-50 is the lowest; accordingly, its corrosion resistance is the best.

Concentrations of Al and Mg in the Fe-spinel increased in this process, and the concentration of Cr in spinel decreased. This can be explained by the increasing of trivalent oxides (Al 2 O 3 and Fe 2 O 3) in the high Al 2 O 3 containing slag. More bivalent oxide (MgO) from the refractory was consumed in forming the spinel phase.

Phase diagram is a graphical representation of the physical states of a substance under different conditions of temperature and pressure. A typical phase diagram has pressure on the y-axis and temperature on the x-axis. As we cross the lines or curves on the phase diagram, a phase change occurs. In addition, two states of the substance coexist ...

The corrosion of iron (and other active metals such as Al) is indeed rapid in parts of the Pourbaix diagram where the element is oxidized to a soluble, ionic product such as Fe 3+ (aq) or Al 3+ (aq). However, solids such as Fe 2 O 3 , and especially Al 2 O 3 , form a protective coating on the metal that greatly impedes the corrosion reaction.

Although precipitation of α-Al 12 (Fe, Mn) 3 Si 2 phase takes place at a temperature lower than that of β-Al 5 FeSi phase (Figure 16(b)), it does not seem to have an effective role in porosity formation due to branching which would facilitate the motion of the liquid metal between the script arms as displayed in Figure 16(c).
