This is a first systematic report on the synthesis of completely nanocrystalline metals by high-energy deformation processes. Pure metals with body-centered cubic (bcc) and hexagonal close-packed (hcp) structures are subjected to ball milling, resulting in a decrease of the average grain size to ≈9 nm for metals with bcc and to ≈13 nm for metals with hcp crystal structures.

The grain size was further reduced to 14 nm by milling the as-prepared ferrite particles in a high-energy ball mill. The increase in conductivity of the milled sample was, therefore, attributed to conduction by the oxygen vacancies created by mechanical milling.
