Interstitial Voids in Metals: 2 Types | Metallurgy

Two main types of interstitial voids (between the bigger atoms) occupied by interstitial (small) solute atoms are: 1. Tetrahedral Voids 2. Octahedral Voids. When same sized spheres (hard balls) are packed in three dimensions, void spaces are present between the spheres. These voids are called interstitial voids. The size of the interstitial sites is always smaller than the common five [...]
