Waqaas Ali ENMA-300 Metallography Metallography is basically the study of metals often through the methods of microcopy. Metal surfaces and fractures are examined with the eye or with a magnifying glass or metallurgical or binocular microscope at magnifications less than 10 diameters that unveil valuable information as to the crystalline. Microscopic examination of polished or etched surfaces at magnifications ranging from about 100 to 1,500 diameters, which reveals information as size and shape of grains, distribution of structural phases. Before the preparing the specimen under the microscope, the metal is often grinded, polished and etched to provide better examination. Is then mounted to the microscopes, where it is closely observed using metallographic techniques in identifying alloys and predicting their material properties. There are different types of microscopes that are used in observing the structure of metals. One of which is the optical microscope, which are great for general use. But
