During microstructure analysis of metals and alloys, a microscopic examination is conducted to study the microstructural features of the material under magnification. Thus, the focus of the book is on the integrated microscope system, with foundations in optical theory but extensions into electronic imaging. The properties of a material determine how well it will perform under a given application, and these properties are dependent on the structure of the material. Metallography is the study of the structure of metals and of metal alloys through the examination. This is known as examination of the metal in the aspolished condition.
