Metallurgical Testing typically uses microscopy to provide important information about the structure and properties of metal and alloy samples. These services are also called Metallography Evaluation, Metallographic Examination and Metallurgical Analysis. 1.1 The primary objective of metallographic examinations is to reveal the constituents and structure of metals and their alloys by means of a light optical or scanning electron microscope. Metallography is the study of the physical structure and components of metals, by using microscopy. Ceramic and polymeric materials may also be prepared using metallographic techniques, hence the terms ceramography, plastography and, collectively, materialography.

Metallographic Examination Metallographic examination allows the investigator to distinguish failures caused by stress-corrosion that would occur from the damage caused by severe corrosion, independent of stress. From: Safety Design for Space Systems, 2009
Metallographic exam is often a critical tool for characterizing the extent of cracks and pits. Additionally, this inspection is used to characterize post processing changes due to casting, forging, machining, welding, heat treating and coating.

Metallurgical Testing typically uses microscopy to provide important information about the structure and properties of metal and alloy samples. These services are also called Metallography Evaluation, Metallographic Examination and Metallurgical Analysis. Metallography is often used in comprehensive examination of materials to correlate physical and mechanical properties, and is key to understanding the behavior of the alloys under certain conditions and external stresses.
In special cases, the objective of the examination may require the development of less detail than in other cases but, under nearly all conditions, the proper selection and preparation of the specimen is of major importance. metallographic examination of specimens allows the metallographer to observe and record the crystalline structures and to interpret from them the history of manufacture and use of the material. Metals and alloys often contain features other than grains.
