2. Obtaining nanostructured materials

2.1 Main techniques

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]...
