Alpha iron (α-Fe) 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 … See more At atmospheric pressure, three allotropic forms of iron exist, depending on temperature: alpha iron (α-Fe, ferrite), gamma iron (γ-Fe, austenite), and delta iron (δ-Fe). At very high pressure, a fourth form exists, See more Epsilon iron / Hexaferrum (ε-Fe) At pressures above approximately 10-13 GPa and temperatures up to around 700 K, α-iron changes into a See more • Tempering (metallurgy) See more Melting and boiling points The melting point of iron is experimentally well defined for pressures less than 50 GPa. For greater … See more WebAlthough BCC has more total room for interstitial atoms, FCC has the largest particular interstitial site (octahedral). This can have a large impact in …

The packing is more efficient (68%) than simple cubic and the structure is a common one for alkali metals and early transition metals. The primary phase of low-carbon or mild steel and most cast irons at room temperature is ferromagnetic α-Fe.
