Metallography consists of the microscopic study of the structural characteristics of a metal or an alloy. The microstructure reveals the mechanical and thermal treatment of the metal and it is possible to predict its expected behaviour under a given set of conditions. ... inclusion like mill scale, contaminant like dirt, etc. In
