Lectures
1. Introduction (definition of forming, fundamental terms, Queen Steel).
2. ABC of forming theory 1 (crystallic structures of metals, plastic deformation mechanisms, hypotheses of plasticity).
3. ABC of forming theory 1 (stress, strain, strain friction, strain rate, flow stress, state of stress and strain, fundamental laws of plastic deformation).
4. Metallurgical formability 1 (hardening and softening processes in steels),
5. Metallurgical formability 2 (influence of chemical composition, of state of structure, of temperature, strain and strain rate on formability, basic of controlled forming of steels),
4. Heating of metals 1 (forming temperatures, physical fundaments of heating, concomitant phenomena of heating).
5. Heating of metals 2 (means of heating, furnaces).
6. Rolling 1 (theoretical aspects of rolling, deformation zone, bite of rolls).
7. Rolling 2 (classification of rolling mills, equipment of rolling mills).
8. Rolling 3 (most significant rolling mills in CR).
9. Forging 1 (basics of forging, free (smith) forging, degree of forging).
10. Forging 2 (die forging, equipment of forge, most significant forges in CR).
11. Cold Forming 1 (surface treatment before cold forming).
12. Cold Forming 2 (rolling, wire drawing, extrusion).
