Fcc tetrahedral interstitial sites
WebFor FCC structure, a.) Calculate the ratio of the tetrahedral-site radius rt to the FCC-atom radius r ; b.) Calculate the ratio of the octahedral-site radius ro to the FCC-atom radius r. Please draw schematic(s) showing how you calculated the radii of these two types of interstitial sites. Thanks in advance! WebNov 18, 2024 · For both FCC and BCC crystal structures, there are two different types of interstitial sites. In each case, one site is larger than the other, and is normally occupied by impurity atoms. For FCC, this larger one is located at the center of each edge of the unit cell; it is termed an octahedral interstitial site.
