The mechanism by which metals deform is via the motion of linear defects at the atomistic scale, called dislocations (see the figure). In metals, dislocations are usually mobile, and their motion provides for the irreversible shifting of atomic planes in a process called slip, resulting in plastic deformation. Without the mechanism of moving dislocations, metals would fail under mechanical
