Crystal structure - Wikipedia, the free encyclopedia
In mineralogy and crystallography, a crystal structure is a unique arrangement of atoms in a crystal. A crystal structure is composed of a motif, a set of atoms arranged in a particular way, and a l...

A crystal structure found in some of the common elemental metals; within the cubic unit cell atoms are located at all corner and face-centered positions. Roughly 20% of the elements crystallize with face centred cubic structures.

Definition: An arrangement of atoms in crystals in which the atomic centres are disposed in space in such a way that one atom is located at each of the corners of the cube and one at the centre of each face. Steel in the face-centred cubic arrangement is termed austenite.

In the Face Centered Cubic (FCC) unit cell there is one host atom at each corner and one host atom in each face. ... The corner and face atoms touch along the face diagonal, and it is easy to show that the cube edge (a) is about 2.8r. Thus, the corner atoms do not touch one another.

SPHERES can be stacked into two close-packed crystalline arrangements, face-centred cubic (f.c.c.) and hexagonal closed-packed (h.c.p.), which have identical close-packed volumes1 and very similar equations of state2.

The noble metals (copper, silver and gold) crystallise in the face-centred cubic (f.c.c.) structure but attempts to calculate their cohesive energy1 and stacking fault energies2 predict that the stable structure is the hexagonal close packed (h.c.p.). By considering a collinear three-ion interaction I have identified...

Magnetic after-effect measurements of H, D and T in both dilute Ni alloys and in a face-centred cubic Co alloy at low temperatures have revealed significant isotope effects of the jump frequencies nu , the pre-exponential factors nu 0 and the activation energies Q. The isotope effects are much more pronounced between H...
