Iron has a body centered cubic unit cell
WebThe first three forms are observed at ordinary pressures. As molten iron cools past its freezing point of 1538 °C, it crystallizes into its δ allotrope, which has a body-centered cubic (bcc) crystal structure. As it cools further to 1394 °C, it changes to its γ-iron allotrope, a face-centered cubic (fcc) crystal structure, or austenite. At ... WebBody-Centered Cubic (BCC) Face-Centered Cubic (FCC) Hexagonal Close-Packed (HCP) Here are the details for each of the three crystal structures: Body-Centered Cubic (BCC): Unit Cell: Each corner of the cube has an atom, and there is one additional atom in the center of the cube. The atoms touch along the body diagonal. Example metal: Iron (Fe ...
