Nanocrystalline metals prepared by high energy ball milling

Abstract 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.
