Abstract This is a first systematic report on the synthesis of completely nanocrystalline metals by highenergy deformation processes. Pure metals with bodycentered cubic (bcc) and hexagonal closepacked (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.

Ball Mill. The degree of milling in a ball mill is influenced by; Residence time of the material in the mill chamber. The size, density and number of the balls. The nature of the balls (hardness of the grinding material) Feed rate and feed level in the vessel. Rotation speed of the cylinder. Several types of .
Highenergy ball milling is a simple, effective and productive way to produce various nanocrystal powders in highenergy planetary ball mills [7]. High reactivity and small particle size can facilitate the production of high density ceramics at low sintering temperatures [8]. Therefore, the SPS along with highenergy ball milling has

Planetary Ball Mills are used wherever the highest degree of fineness is required. In addition to wellproven mixing and size reduction processes, these mills also meet all technical requirements for colloidal grinding and provide the energy input necessary for mechanical alloying.
The highenergy ball milling technique is simple and has high potential to scale up to produce tonnage quantities of materials [8]. However, a serious problem of this technique is the contamination from milling media (balls and vial) and/or atmosphere.
