Subject aims expressed by acquired skills and competences
The course is aimed at a deeper understanding of the relationship between design, manufacturing processes and properties of materials that are applied in the automotive, aerospace, energy or engineering industries. Various manufacturing technologies including progressive methods of metallurgy such as induction skull melting, centrifugal casting, electron beam floating zone melting, plasma metallurgy, melt spinning, strip casting, atomization, further composites manufacturing processes, additive manufacturing technologies, methods of forming thin films, etc. The fundamental principles of given technologies, their advantages and disadvantages, the economic aspects, the suitability/proposal of the processes for the particular materials in order to achieve their required properties will be discussed. New areas of advanced science and technology, for example, semiconductors, microelectronics, optoelectronics, superconducting materials, vacuum technology, nuclear metallurgy, space industry, require materials, metals and their special alloys and compounds with high chemical purity and defined physical and structural parameters and specific applied properties. Therefore, the attention will also be paid to the manufacturing processes of high purity materials via suitable physical, physico-chemical and metallurgical methods (e.g. sorption, extraction, crystallization from aqueous solutions, electrolysis, crystallization from melts, evaporation, condensation and transport reactions, electro-transport, diffusion separation of substances, removal of gases from melts and vacuum refining of metals).
The students will be able:
- to characterize given manufacturing processes of pure metals, alloys, compounds and composites, including their advantages and disadvantages with regard to obtaining materials with specific utility properties and quality,
- to critically analyze alternative manufacturing processes,
- to define / specify material properties affecting the choice of the manufacturing process,
- to interpret the manufacturing processes of materials in a wider context,
- to select a suitable production process for obtaining a material with required properties,
- to take into account all aspects of the manufacturing process of material or component, including subsequent recycling or disposal,
- to consider a choice of suitable physical, physico-chemical and metallurgical methods for particular cases of synthesis or purification of metals, alloys and compounds,
- to define the thermodynamic and kinetic factors necessary for the assessment of refining effect in the area of the metallurgy of pure metals.

Summary
Předmět je zaměřen na hlubší pochopení vztahu mezi designem, výrobními procesy a vlastnostmi materiálů, které jsou aplikovány zejména v automobilovém, leteckém, energetickém či strojírenském průmyslu. Budou popsány různé způsoby výroby materiálů, zahrnující progresivní metody metalurgie jako tavení ve studeném kelímku, odstředivé lití, elektronové zonální tavení, plazmová metalurgie, melt spinning, strip casting, atomizace, dále výrobní procesy kompozitních materiálů, technologie aditivní výroby, metody přípravy tenkých vrstev, aj. Budou diskutovány principiální aspekty daných technologií, jejich výhody a nevýhody, ekonomické hlediska, vhodnost/návrh procesů pro konkrétní materiály z hlediska dosažení jejich požadovaných vlastností. V nových perspektivních oblastech vědy a techniky, jakými jsou např. polovodičová technika, mikroelektronika, optoelektronika, technika supravodivých materiálů, vakuová technika, jaderná metalurgie, kosmická a technika jsou vyžadovány materiály, kovy a jejich speciální slitiny a sloučeniny o vysoké chemické čistotě s definovanými fyzikálními a strukturními parametry a specifickými užitnými vlastnostmi. Proto bude pozornost věnována i procesům přípravy vysoce čistých materiálů pomocí fyzikálních, fyzikálně-chemických a metalurgických metod (např. sorpce, extrakce, krystalizace z vodných roztoků, elektrolýza, krystalizace z tavenin, vypařování, kondenzace a transportní reakce, elektropřenos, difuzní dělení látek, odstraňování plynů z tavenin i rafinace kovů ve vakuu, aj.)
