"WebFCC means “Face-Centered Cubic.” It is one of the most common–and most stable–crystal structures. To understand what the FCC crystal looks like, imagine a cube with an atom on each corner of the cube, and each face of the cube. That’s what FCC is! γ’ is an intermetallic compound, with L1 2 structure. This is an ordered FCC arrangement. " - Fcc metallurgy

WebIt is the distance between lattice points (centres of the atoms) along the direction. For example, [110] direction in FCC unit cell, Fig. 1.54 (a). Starting from 0, 0, 0, the next lattice point is at the centre of a face, or at 1/2, 1/2, 0 site. The distance between the lattice points is therefore one- half of the face diagonal, or ½ √2a.
