Hexaferrum and epsilon iron are synonyms for the hexagonal closed packed phase of iron that is stable only at extremely high pressure. At a pressure of 130 kbar and room temp, the Bcc ferrite powder transformed to the Hcp phase. When the pressure was lowered, epsilon Fe transformed back to FerritRead more
Hexaferrum and epsilon iron are synonyms for the hexagonal closed packed phase of iron that is stable only at extremely high pressure.
At a pressure of 130 kbar and room temp, the Bcc ferrite powder transformed to the Hcp phase. When the pressure was lowered, epsilon Fe transformed back to Ferrite rapidly.
At pressures above approximately 10 GPa and temperatures of a few hundred kelvin or less, α-iron changes into a hexagonal close-packed (hcp) structure, which is also known as ε-iron or hexaferrum
