WebFCC and HCP are both close-packed with a 74% atomic packing factor, 12 nearest neighbors, and the same interstitial sites. However, HCP only has 3 slip systems, while FCC has 12 slip systems, which lead to very different mechanical properties. The most direct difference between FCC and HCP crystals is in the atomic arrangements. WebIn FCC, there are 12 nearest-neighbors. When distorting one direction of a cube, the body-centered tetragonal bridges the space between BCC and FCC.
