WebMar 6, 2024 · The calculated melting lines of iron from the bcc, fcc, and hcp phases are shown in Figs 1, 2 and 3. Figure 3: Calculated phase diagram of iron at pressures up to 350 GPa ... Below 912 °C (1,674 °F), iron has a body-centered cubic (bcc) crystal structure and is known as α-iron or ferrite. It is thermodynamically stable and a fairly soft metal. α-Fe can be subjected to pressures up to ca. 15 GPa before transforming into a high-pressure form termed ε-Fe discussed below. Magnetically, α-iron is paramagnetic at high temperatures. However, below its C…
