The Body-Centered Cubic (BCC) structure is a type of crystal lattice found in some metals, where atoms are arranged at the corners of a cube with one additional atom located at the center of the cube. This arrangement allows for efficient packing of atoms, contributing to the material's properties, such as strength and ductility. BCC structures are commonly found in metals like iron, chromium, and tungsten. The unique arrangement of atoms in BCC affects how these metals respond to stress and temperature changes, making them suitable for various industrial applications, including construction and manufacturing.
