bhadeshia123 | Pure iron - the phase diagram - terapascal pressures, 20000 K @bhadeshia123 | Uploaded March 2020 | Updated October 2024, 1 hour ago.
Pure iron has many allotropic forms, which switch between one -another depending on pressure and temperature. The conventional diagram does not extend to sufficiently high values of T, P. Recent work has extended the diagram with some surprising results, showing that hcp iron is not necessarily the most stable form at terapascal pressures and temperatures as high as 20,000 K. The subject has relevance not only to our own Earth, but exoplanets that are much larger than the Earth.
