A series of 19 alloys was produced and heat-treated at temperatures in the range from 600 to 1100 °C for up to 5000 h. Sep 05, 2020 · Correct interpretation of Fe-Al phase diagram is of critical importance for applying Fe-Al alloys in most applications. Fe-rich part of binary Fe-Al phase diagram consists of three main phases: the disordered A2-phase (α-Fe, space group Im3m), the ordered B2-phase (FeAl, space group Pm3 m) and the ordered DO 3-phase (Fe 3. 2.2. Al-Fe-^Mg PHASE DIAGRAM This phase diagram can be used to analyze the effect of iron on the phase compo sition of Al-Mg alloys with low concentrations of silicon and manganese. Examples of such alloys are given in Table 2.5. No ternary compounds have been found in the ternary Al-Fe-Mg system

Si/Al Phase Diagram Most Si/Al alloys are cast near this eutectic point, they are cheap to manufacture; but cuboid Si flakes cause brittleness. Doping with 0.01% Na alters the compositional and temperature of the eutectic point (red lines): Alloy 2, which has the same relative amounts of Si and Al, now preciptates in a hypoeutectic fashion. % Al and Fe. In addition to equilibria with the O 1 and η phases, this phase also participates in equilibria with the < Al 13 Fe 4 >, θ phase (based on Al13Cr2), and aluminum-based solid solution.

The diffractogram of sample #12 (Al 48 Fe 37 Si 15) annealed at 900 °C showing the three-phase field of [AlFe + Al 5 Fe 2 + τ 12] and with τ 12 as the main phase is given in Fig. 8. The percentage of phases given in Fig. 8 , correspond to the refined area of the powder pattern and are in good agreement with expectations from the lever rule. 1 The specific phase Al 5 Fe 2 is important as it forms at the junction layers of Fe with Zn during galvanizing treatments. Our own interest in the Al-Fe phase diagram derives from its complex and.

the Fe-Al-Zr phase diagram,[34] values of 1.8, 2.2, 0.7 at.% were given for the widths of the homogeneity ranges of these intermetallic compounds at 1000 C. Summarizing the above and having in mind that several lines in the Al-rich part of the Fe-Al phase diagram are still The thermodynamic models used to describe the Fe-Al phase diagram are studied in detail. We calculate the phase diagram of Fe-Al within the Bragg-Williams approximation and the tetrahedron approximation of the cluster-variation method, including nearest- and next-nearest-neighbor chemical and magnetic interactions. In contrast to previous calculations performed within the Bragg-Williams. 1.1. Al-Fe-Si PHASE DIAGRAM The Al-Fe-Si system is the basic system for the structure analysis of commercial aluminum alloys of the 8111 type, and binary Al-Si alloys which, as a rule, contain an iron impurity (Table 1.1). The aluminum corner of the Al-Fe-Si phase diagram is considered in detail by Phillips (1959), who gives the isotherms of. For the phase diagram calculations of Fe-Cr-Al alloy, we only consider bcc and bcc superstructures. The energy convex hulls of Fe-Cr, Fe-Al, and Cr-Al are shown in Fig. 2, and the formation energies for non-bcc stable structures FeAl 6-Cmcm, Cr 2 Al-I4/mmm, CrAl 3-I4/mmm and Cr 7 Al 45-C2/m from USPEX , calculations are also included. These non-bcc stable phases are consistent with the phases.

Though, it is noted that according to the phase diagram shown in Fig. 1 a two-phase field α-(Fe,Al)+Fe 3 Al exists which apparently extends to even lower Al contents than shown in Fig. 1. At 300 °C Ikeda et al. [24] found the A2/A2+D0 3 phase boundary at about 17 at.% and according to the slope of their data this phase boundary could extend.
