Allotropy of Iron: Thermodynamics and Crystal Structures Metallurgy

WebIron can exist in two main modifications. Below 911 °C the stable modification is α-iron with a body centered cubic (bcc) structure, above 911 °C the stable modification is γ-iron, the face centered cubic (fcc) structure. A third modification is found at higher temperatures (δ-iron) for a bcc structure with different crystallographic ... 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).
