If a material on the atomic level is characterized by a uniform lattice orientation (no grain boundaries), it is also called a single crystal. If such a single crystal is deformed under tension, inclined rings are formed in the deformation region. This can be clearly seen from the copper single crystal shown in the figure below. gls shipping label roll long
