Learning outcomes of the course unit

Successful graduate of the course is ready to:

1) Based on composition information, describe the phase composition, and chemical nature of phases present in an alloy.
2) Explain differences of structures of most common steel grades, estimate their fundamental properties (weldability, quenchability, tensile strength, corrosion resistance) according their standardized designation .
3) Describe the specifics of brasses, bronzes, duralumins and other nonferrous alloys.
4) Describe the basic meanings of research of metallic materials (metallography, analytic microscopy, corrosion tests, mechanical properties).

Course curriculum

1. An introduction – pros and contras of metallic materials, topics of recent research, fundamental materials´ characteristics.
2. Metal bond – deduction by method MO-LCAO, properties. Arrangement of atoms in crystal lattice.
3. Real structures – defects, their formation and their meaning for chemical, corrosion and mechanical properties of materials.
4. Alloys – solid solutions, intermetallic compounds, Hume – Rothery rules for solid solutions (based on chemical nature of mixed metals). Properties of intermetallic compounds.
5. Equilibrium binary phase diagrams, derivation of composition of alloys.
6. Kinetics and thermodynamics of phase transformations. Diffusion, its mechanisms and quantitative description (during coating formation).
7. Electrochemical properties of metals, corrosion, high-temperature corrosion. Chemistry of corrosion products.
8. Corrosion protection – chemical technology of surface treatments and pretreatments.
9. Means of research of metallic materials, corrosion mechanisms and surface treatments.
10. Basic steel grades. Their composition and information contained in their standardized designation.
11. Nonferrous metals and their alloys: Copper, brasses, bronzes. Aluminum, duralumins.
12. Nonferrous metals and their alloys: Magnesium, zinc, titanium, chromium, nickel, Summary of other metals and their use.

Aims

Target audience is presented by students aimed on materials´ chemistry. Goal of the lecture is to introduce real metallic structures in the context of previously taught chemical disciplines. The secondary goal is then the knowledge of most important properties of materials, their practical use and systematic categorization of both ferrous and nonferrous alloys.

Specification of controlled education, way of implementation and compensation for absences

Subject is taught as lectures with voluntary attendance. According recent plan of study program there is no form of compulsory tasks in this subject.
