WebThe Face-Centered Cubic (FCC) unit cell can be imagined as a cube with an atom on each corner, and an atom on each face. It is one of the most common structures for metals. FCC has 4 atoms per unit cell, lattice constant a = 2R√2, Coordination Number CN = 12, and Atomic Packing Factor APF = 74%. FCC is a close-packed structure with ABC-ABC stacking. Web1. The hexagonal structure of alternating layers is shifted so its atoms are aligned to the gaps of the preceding layer. 2. The atoms from one layer adjust themselves in the empty space between the atoms of the adjacent layer just like in the F.C.C structure. However, instead of being a cubic structure, the pattern is hexagonal.
