Sintering occurs by diffusion of atoms through the microstructure. CSCNTs exhibit semiconducting behavior because of the stacking microstructure of graphene layers. Each powder particle contains aluminium between beryllium dendrites producing a uniform microstructure. Transmission electron microscopy can be used to observe dislocations within the microstructure of the material. Enamel is made up of a very organized hierarchical microstructure of carbonated hydroxyapatite nanocrystals. They possess an austenitic microstructure, which is a face-centered cubic crystal structure. This forms a layered microstructure called pearlite. Similarly, the hardenability is limited by the continuous martensitic microstructure formed when cooled very fast. The main goal of process annealing is to produce a uniform microstructure. This eutectoid mixture will then crystallize as a microstructure of pearlite. White cast iron is composed mostly of a microstructure called ledeburite mixed with pearlite. It is especially suitable for revealing the microstructure of carbon steels. Other conventional techniques for improving the microstructure are thermal processes. A micrograph contains extensive details of microstructure. It was then used for a scanning electron microscope study of "Anchiornis" feather microstructure.
