Entry knowledge

Knowledge of inorganic chemistry, structure of materials and physical chemistry.

Rules for evaluation and completion of the course

Credit will be awarded after submitting all protocols and passing the credit test.
The exam is oral after passing the credit and passing the placement test. The weight of the placement test is 10%, the credit rating is 40% and the oral examination weight is 50% of the total evaluation. Oral examination is possible only after passing the credit from laboratory exercises.
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.

Aims

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).
Successful graduates of the course will be able to:

1) Based on the chemical composition of the material, describe the phase structure, determine the chemical nature of the phases present in the given alloy,
2) Explain differences in the structure of the main types of steels and determine their basic utility properties (strength, corrosion resistance, weldability, hardenability) from their normative designation,
3) Describe the specifics of brass, bronze, duralumin and other non-ferrous metal alloys,
4) Describe the basic procedures in the research of metallic materials (metallography, analysis microscopy, corrosion tests, mechanical properties).
