WebApr 6, 2024 · The hcp structure has 8 spheres per unit cell whereas the ccp structure has 4 spheres per unit cell. Both the hcp & ccp structures have a packing efficiency of 74 percent. Thus, the packing fraction would also be the same i.e. both the structures have the packing fraction of 0.74. 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 …

WebFCC is one of the most stable crystal structures and has the highest packing density. In some textbooks, FCC may also be abbreviated as CCP, which stands for Cubic Close-Packed. The face-centered cubic cell belongs to space group #225 or , Strukturbericht A 1, and Pearson symbol cF4 . Cu is the prototype for FCC. WebComparison of fcc/ccp and hcp Since both structures are composed of stacked hexagonal layers, we expact them to be similar - and they are. There are some subtle differences however.
