Been Carried Out In Highenergy Ball Mills

In the highenergy ball milling process, coarsegrained structures undergo disassociation as the result of severe cyclic deformation induced by milling with stiff balls in a highenergy shaker mill 8, 9. This process has been successfully used to produce metals with minimum particle sizes from 4 to 26 nm.
