On the micrometer scale deformation properties of metals change profoundly: The smooth and continuous behavior of bulk materials often becomes jerky due to random strain bursts of various sizes. The reason for this phenomenon is the complex intermittent redistribution of lattice dislocations (which are line-like crystal defects responsible for the irreversible deformation of crystalline materials) due to external loading, which is also the cause of the formation of the uneven step-like surface upon deformation.
