The target group are students focused on material chemistry. The aim of the course is to acquaint students with real structures of metallic materials in the context of already acquired chemical education. The secondary objective is then knowledge of the most important properties, the resulting predominant practical use and in industrial practice systematization of sorting of alloys based on iron and non-ferrous metals.
The aim of the laboratory exercise is to teach students to master basic metal sample preparation for observation of its structure, documentation and interpretation of results. Another goal is application of knowledge acquired in theoretical subjects in real experiments, especially confrontation of observed structure and phase diagrams, relation of structure and properties (mechanical, corrosion).

Part of the course is realized in the form of a lecture in which participation is voluntary.
In the laboratory part of the course 100% attendance is compulsory. The form and time of compensation in case of excusable absence (family death, medical restriction confirmed by the doctor, national representation, school representation, carrier failure confirmed by the carrier) are set by the teacher.
