Obtaining nanostructured materials
Material properties of nanostructured materials

Two ways of obtaining nanostructured materials are possible:

• They can be produced by the progressive deposition of atoms (method bottom up, upwards),

• They can be produced by transforming the macroscopic structure (method top down, downward).

By using only the main techniques; inert gas condensation and electroplating fall within the first methods, trituration (or mechanical alloying), the crystallization of amorphous solids and severe deformations are secondary methods. Article [MA 4 026] discusses in detail a certain number of these techniques. They will therefore be merely mentioned here. However, processes by electrolysis, crystallization...
