  skos:definition "Le concept de microstructure peut se définir indépendamment des matériaux considérés. Schatt et Worch la définissent ainsi : « Le concept de microstructure désigne la conformation d'ensemble d'une particule de matière, dont l'orientation est, en première approximation, homogène, au regard de sa composition et de l'arrangement de ses composants […]. La microstructure se caractérise par la forme, la taille, les proportions et la texture des phases. » Les zones de la microstructure, appelées cristallites (grains, charges ou zones amorphes) sont généralement de taille microscopique et peuvent être caractérisées, aussi bien qualitativement que quantitativement, au microscope optique. Les matériaux monocristallins et amorphes ne présentent aucune microstructure visible au microscope optique.

The microstructure of a material can strongly influence physical properties such as strength, toughness, ductility, hardness, corrosion resistance, high/low temperature behaviour or wear resistance. Microstructure at scales smaller than can be viewed with optical microscopes is often called nanostructure, while the structure in which individual atoms are arranged is known as crystal structure. The nanostructure of biological specimens is referred to as ultrastructure. A microstructure’s influence on the mechanical and physical properties of a material is primarily governed by the different defects present or absent of the structure. These defects can take many forms but the primary ones are the pores. Even if those pores play a very important role in the definition of the characteristics of a material, so does its composition. In fact, for many materials, different phases can exist at the same time. These phases have different properties and if managed correctly, can prevent the fracture of the material.
