According to the standard phase diagram, at 912 °C this phase transforms to a face-centered cubic (fcc) lattice (space group Fm3m), the so-called γ-phase [2]. At 1394 °C γ-Fe may transform back to the bcc structure, so-called δ-phase, the latter finally melting at 1538 °C...
Structure and energy of the edge-dislocation for both the bulk and nanoparticles of iron were investigated. A detailed energy plots for H and hydrogen bond pair was observed near the dislocation core. The phonon spectrum and thermodynamic properties of the BCC-Iron perfect crystal were calculated....
3.1 Equilibrium diagram The copper-iron system phase diagram is shown in Fig. 1. In this calculation, we used SSOL4(4) as a thermodynamic database. Figure 1(b) shows an expanded view of the region around the range of the C194 iron composition. As shown, in the cooling process fcc Fe...

When the iron is at a high temperature, 1550°C, the Ellingham diagram indicates that CO is a more stable oxide than SiO2. Thus carbon oxidises preferentially and is therefore lost at a higher rate than silicon, as is seen in Figure 6.28. Here the blowing of air on to the surface of...
Figure 103 illustrates the Fe-Al phase diagram. The Fe3Al phase, with a DO3 ordered structure, corresponds to Al concentrations ranging from approximately 22 at.% and 35 at.%. A phase transformation to an imperfect B2 structure takes place above 550 °C. The latter ultimately transforms to ...
