Web3. Body Centered Cubic (BCC) Not close packed - atoms at corners and body center of cube. # atoms/unit cell = 2. Coordination number = 8; less efficient packing (68%). The atoms are only in contact along the body diagonal. Examples of BCC structures include one form of Fe, V, Cr, Mo, W. WebApr 19, 2024 · (2) Body Centered Cubic (bcc) Structure: (1) A more efficiently packed cubic structure is the "body-centered cubic" (bcc). (2) The first layer of a square array is expanded slightly in all directions. Then, the second layer is shifted so its spheres nestle in the spaces of the first layer.
