خلاصه: In order for a material to be defined nanocrystalline the
size of its grains must be of the order of less than 100 nm.
Such materials can be constituted by one or more phases
distributed in one, two, or three dimensions. Examples are
nanowires, layers either deposited on top of a substrate as
coatings or stacked in suitable sequences, and bulk objects.
If the material is fully made of nanograins the number density of crystals scales with their size (e.g., it can range from 1025 to 1021 m−3 for sizes of 5 and 100 nm respectively).
