Mechanical Annealing of a Nickel Nanopillar

Caption

Compression of a nickel pillar whose free end has a diameter of about 150 nanometers: before compression (right) the pillar has a high density of defects, visible as dark mottling. After compression all the defects have been driven out, a previously unobserved process known as "mechanical annealing."
