Subject syllabus:
1. Assortment of formed products and their basic practical applications, summary of processing technologies
2. Conditions for plastic deformation beginning. Theoretical definitions of stress state, stress and strain intensity.
3. Plastic deformation basic laws, deformation in hot and cold conditions, non-homogeneity of strain, influence of friction. Recovery processes – restoration, recrystallisation and grain growth.
4. Rolling and forging: basic characteristics (deformation zone, practical equipment, production of rolled semi-products, long and flat products, wire rolling, forged pieces production).
5. Other forming methods characteristics (drawing, extrusion, profiling…) and non-conventional forming methods.
6. Forming of non-ferrous metals and alloys
7. Final treatment and further modifications of products
8. Procedures of casting production description of individual production units. Production of castings using permanent metal mold and lost sand mold.
9. Molding wih split pattern, cores using. Hand and mechanized sand molding. Precision casting with lost wax pattern, Lost Foam, V-process. Production of castings using gravity casting, high and low pressure die casting, centrifugal casting.
10. Melt fluidity and castability. Running system design depending on the type of poured metal. Running system calculation. Calculation of metalostatic pressure and buoyancy .
11. Castings crystallization and solidification. Thermodynamic conditions of crystallization. Solidification time, shape of castig and mould material, thermal diffusivity of the mould.
12. Solidification shrinkage and its consequence – shrinkage cavities, porosities – causes and prevention. Hot spots – facing their consequences, directional solidification, feeding, calculation of the riser volume.
13. Linear contraction of the casting, hot tearing, cold cracking, residual stresses.
14. General design of metal casting production. Methods of Rapid Prototyping. Methods of castings finnishing.
