It is an … There are two simple regular lattices that achieve this highest average density. They are called face-centered cubic (FCC) (also called cubic close packed) and hexagonal close-packed (HCP), based on their symmetry. Both are based upon sheets of spheres arranged at the vertices of a triangular tiling; they differ in how the sheets are stacked upon one another. The FCC lattice is also known to m…
WebThe DHCP crystal structure is similar to FCC or HCP, but it uses a 4-layer stacking pattern ABAC-ABAC, instead of FCC’s ABC-ABC or HCP’s AB-AB stacking pattern. The double hexagonal close-packed cell belongs to … A stacking fault is a type of crystallographic defect, where a plane of atoms is in the wrong position. For example, you know that FCC has stacking order ABC-ABC-ABC-ABC. A stacking fault could be an extra plane of atoms, such as ABC-B-ABC-ABC, or a removed plane of atoms, such as ABC-BC-ABC-ABC.
