Possible Slip Systems in Body Centered Cubic Iron

Stability of body-centered cubic iron-magnesium alloys in the Earth's inner core.

The composition and the structure of the Earth's solid inner core are still unknown. Iron is accepted to be the main component of the core. Lately, the body-centered cubic (bcc) phase of iron was suggested to be present in the inner core, although its stability at core conditions is still in discussion. The higher density of pure iron compared with that of the Earth's core indicates the presenc...

Title A universal relation for the stress dependence of activation energy for slip in body-centered cubic crystals

Grain boundary energies in body-centered cubic metals

Atomistic simulations using the embedded atom method were employed to compute the energies of 408 distinct grain boundaries in bcc Fe and Mo. This set includes grain boundaries that have tilt, twist, and mixed character and coincidence site lattices ranging from R3 to R323. The results show that grain boundary energies in Fe and Mo are influenced more by the grain boundary plane orientation tha...

Cryogenic nanoindentation size effect in [0 0 1]-oriented face-centered cubic and body- centered cubic single crystals

Rotation-limited growth of three-dimensional body-centered-cubic crystals.

According to classical grain growth laws, grain growth is driven by the minimization of surface energy and will continue until a single grain prevails. These laws do not take into account the lattice anisotropy and the details of the microscopic rearrangement of mass between grains. Here we consider coarsening of body-centered-cubic polycrystalline materials in three dimensions using the phase ...
