At least four allotropes of iron differing atom arrangements in the solid are known, conventionally denoted α, γ, δ, and ε.
The first three forms are observed at ordinary pressures. As molten iron cools past its freezing point of 1538 °C, it crystallizes into its δ allotrope, which has a body centered cubic bcc crystal structure. As it cools further to 1394 °C, it changes to its γ iron allotrope, a face centered cubic fcc crystal structure, or
