Lectures: 1. Internal structure of metals - body-centered cubic lattice, face-centered cubic lattice, hexagonal close-packed lattice. Crystal lattice defects. 2. Alloys of metals, solid solution (substitutional, interstitial), binary equilibrium diagrams of alloys (with complete solid solubility, with limited solid solubility, with complete solid insolubility), liquidus and solidus curves. Utilization of these diagrams in technology. 3. Iron and its alloys. Pure iron. Influence of carbon on the iron alloys (cementite, graphite). Phase diagrams Fe - C (metastable and stable). Characteristics of materials on the base Fe - C (steels, irons). Grades of steels, classification of irons, their properties and importance for machine parts productions. 4. Non-ferrous metals and their alloys (alloys of copper, aluminium, etc.). Thermal treatment. Their applicability in the technical practice. 5. Casting. Used casting alloys and their properties. Melting, modification of melt before casting. Design of castings from the technological point of view. 6. Welding of metals and its importance. Basic terms, terminology of welded joint, classification of welding methods. Weldability of metals and alloys. 7. Brazing of metals - types, fluxes and process technology. Cutting of material - cutting by oxygen, plasma, laser and water jet. 8. Forming of metals and alloys. Alloys suitable for forming. Classification of metal forming processes (cold and hot forming). Bulk forming - forging, rolling, extrusion. Sheet metal forming - shearing, bending, press braking, drawing and straightening. 9. Corrosion of metals, its principle and types, corrosion resistance of metals, methods of corrosion resistance. 10. Surface treatments methods. Preliminary modifications of surface, metallic coatingsnon-metallic inorganic coatings, organic coatings. 11. Adhesive bonding technology. Advantages and disadvantages of bonded joints. 12.

Learning outcomes
|
Ain of course is to familiarize students with basic materials that are commonly used in the technical practice and their technological processing. There is presented and introduced internal structure of metals having influence on material properties, mechanisms of alloys creation - namely both for iron and non-ferrous material. From the technologies there are given basics of cutting and non-cutting technologies with their advantages, disadvantages and specifics. Principles of the individual technologies are shown as examples during tutorials.
Basic knowledge about materials in technical practice, overview of cutting and non-cutting technologies, heat treatment, surface treatment and additive technologies.
