WebFeb 14, 2024 · The APF for the FCC crystal structure is 0.74, which is greater than the 0.68 factor for the BCC structure. The APF of 0.74 is for the closest packing possible of “spherical atoms.” Many metals such as aluminum, copper, lead, nickel, and iron at elevated temperatures (912°C to 1394°C) crystallize with the FCC crystal structure.
WebAug 31, 2024 · You can see that, if the fcc cell dimensions are taken to be of unit length, the body-centred tetragonal cell has dimensions 1 2 × 1 2 × 1. So scaling the fcc z axis by a factor 1 2 will produce a regular bcc lattice; or equivalently elongating a bcc lattice along z by a factor 2 will convert it into fcc. Share. Cite.
