The metals and their alloys are because of their diversity and recyclability today and in the future one of the main groups of substances. Thus, in all technical applications the examination of the macro- and microstructure of metallic materials plays an important role. Different problems require a study and interpretation of the process, which has led to the formation or change in the structure and thus the properties. Through complex metallographic preparation methods, it is possible to make almost all structural constituents visible and microscopically appraisable. From primary gains from production through heat treatment conditions to the finest precipitates at the grain boundaries. Because of the longtime observation and evaluation of metallic materials, there is a variety of standardized procedures for assessing the structure with a direct connection to the mechanical-technical properties of the material.
