WebOct 19, 2024 · Iron (Fe) phases are tightly linked to the preservation rather than the loss of organic carbon (OC) in soil; however, during redox fluctuations, OC may be lost due to Fe phase-mediated abiotic processes. This study examined the role of Fe phases in driving hydroxyl radical ( • OH) formation … 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, epsilon iron (ε-Fe, hexaferrum). Some controversial experimental evidence suggests the existence of a … See more 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 … See more • Tempering (metallurgy) 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 Melting and boiling points The melting point of iron is experimentally well defined for pressures less than 50 GPa.
