Micrography (Microscopy)

Micrography is also the art of using microscopes to make photographs. 'Micrograph' is an image obtained by means of a microscope and contains extensive details that form the features of a microstructure. "Etching" is done to improve contrast between phases by selective attack of some phases using reagents. Micrography is a Metallurgist's forte.

Optical microscope and electron microscope are extensively used in micrography or metallography and are indispensable. A wealth of information can be obtained from a simple micrograph like behavior of the material under different conditions, the phases found in the system, failure analysis, grain size estimation, elemental analysis and so on.
