Crystalline microstructure
WebMartensite in AISI 4140 steel. 0.35% carbon steel, water-quenched from 870 °C. Martensite is a very hard form of steel crystalline structure. It is named after German metallurgist Adolf Martens. By analogy the term can also refer to any crystal structure that is formed by diffusionless transformation. [1] WebThe properties of ceramics, however, also depend on their microstructure. Ceramics are by definition natural or synthetic inorganic, non-metallic, polycrystalline materials. Sometimes, even monocrystalline materials, such as diamond and sapphire, are erroneously included under the term ceramics.

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. See more Microstructure is the very small scale structure of a material, defined as the structure of a prepared surface of material as revealed by an optical microscope above 25× magnification.
