Popis:	A material is an “ultrafine grained material” when substantial deviation(s) of its behaviour is observed compared to the “standard” coarse grained materials properties. In plasticity, ultrafine grained metals and alloys exhibit at room temperature new behaviours such as near-perfect elastoplasticity, strain rate sensitivity and high mechanical performances. For copper, these features are detected for grain size below around 300 nm; this threshold is connected to the length scale associated to the lattice dislocation of the metal, Champion et al [1]. Nanostructured metals and alloys open interesting perspectives of applications as far as their special mechanical behavior can be controlled by orientation of their nanostructure and chemistry.
