Iron bcc to fcc

WebFerrite Iron takes the form of bcc. Face-Centered Cubic (fcc) has eight atoms in the corners of a square cube. However, rather than an atom in the center of the cube like bcc, fcc has an atom in the middle of each of the six faces of the cube. So a fcc unit cell consists of 14 atoms. Austenitic Iron takes the form of fcc. Body-Centered ... WebNov 1, 2008 · Black and white circles represent atoms in the bcc and fcc lattices, respectively. The iron atoms belonging to the bcc or fcc crystal were distinguished by the coordination number of the atoms within 3.20 Å [15].
