Therefore, … WebThese octahedral interstitial sites have a radius of 0.414R, where r is the radius of the lattice atoms. HCP also has 12 tetrahedral sites, which means that a small interstitial atom could fit in 12 positions such that it is equally surrounded by 4 HCP lattice atoms. These tetrahedral atoms can be 0.225R, where r is the radius of the lattice atoms.

"WebAs you may know, the atom that sits in the center of a cube can touch the atoms at all 8 corners. That means that the corner-to-center distance, or ½ of the body diagonal will be the radius of the interstitial site + the radius of the atom. To start, let’s use this “imaginary cube” geometry to determine the corner-to-center distance. " - Radius of face centered cubic
