Fig. 12 Example of unstable rapid fracture in a body-centered cubic (bcc) metal (annealed low-carbon steel). Rapid fracture in this alloy occurs almost completely by microvoid coalescence, but close examination reveals a few areas of brittle cleavage. The bcc structure is not close-packed More

... atoms typically result in a crystalline structure, which in most engineering metals are face-centered cubic (fcc), body centered cubic (bcc), or hexagonal close-packed (hcp) structures. The formation of crystal lattices occurs as a result of bonding between atoms. Strong bonding forces between atoms...
