The goal of materialographic specimen preparation is to reveal the true structure of the specimen, whether it is metal, ceramic, sintered carbide, or any other solid material. The easiest way to accomplish this is with a systematic preparation method. When the work routinely involves examining the same material, in the same condition, achieving the same result each time is desirable. This means that the preparation result must be reproducible. Sample preparation follows certain rules which are valid for most materials. Different materials with corresponding properties (hardness and ductility) respond similarly and require the same consumables during preparation. Therefore, all the materials can be displayed in the Metalogram according to their properties, and not because they belong to a certain material group.
