Thermodynamics and Equations of State of Iron to 350 GPa and
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 Epsilon iron / Hexaferrum (ε-Fe) At pressures above approximately 10-13 GPa and temperatures up to around 700 K, α-iron changes into a hexagonal close-packed (hcp) structure, which is also known as ε-iron or hexaferrum; the higher-temperature γ-phase … See more Melting and boiling points The melting point of iron is experimentally well defined for pressures less than 50 GPa.

From above two parts, it can be found that iron nanoplate and bulk samples transform into FCC and HCP phase respectively under [100] direction compressive loading. The only difference between the two samples is that the former has two free surfaces along its z direction, while the latter ... the prisoner eternally silenced 2017

WebW is the prototype for BCC. The Body-Centered Cubic (BCC) unit cell can be imagined as a cube with an atom on each corner, and an atom in the cube’s center. It is one of the most common structures for metals. BCC has 2 atoms per unit cell, lattice constant a = 4R/√3, Coordination number CN = 8, and Atomic Packing Factor APF = 68%. WebFerrite, also known as α-ferrite (α-Fe) or alpha iron, is a materials science term for pure iron, with a body-centered cubic B.C.C crystal structure. It is this crystalline structure which … http://che.uri.edu/course/che333/Structure sigmund freud awards and achievements
