Summary

The aim of the subject consists in transmitting the broad theoretical knowledge about hot/cold deformation behaviour of the metal materials, about the sophisticated plastometric tests and about study of the structure-forming processes at bulk forming.

Methodology of the complex study of hot deformation behaviour. 4. Influence of friction, additional stresses and state of stresses on forman¨bility of material. 5. Analysis of the hot tensile/compression/torsion test (application, strong/weak points). 6. Survey of the application possibilities of plastometre Gleeble, introduction of the HDS-20 simulator. 7. Comparison of deformation behaviour of austenite and ferrite (sliding systems, deformation resistance). 8. Activation energy at forming, physical sense of the Zener-Hollomon parameter, dynamic softening. 9. Matahematical description of the kinetics of postdynamic softening processes (Avrami’s equation). 10. Principles of controlling the structure development din the course of hot forming (effecting the recrystallization and phase transformations). 11. Types and kinetics of precipitation, effect of the various particles on deformation behaviour. 12. Influence of the chemical composition on phase structure and deformation behaviour of material. 13. Effect of the state of structure on deformation behaviour (ingots, concast products, worked structure, grain size). 14. Influence of the thermomechanical factors on deformation behaviour (temperature, strain rate, deformation history). 15. Mathematical models of cold/hot deformation resistance (Matematické modely deformačních odporů za studena a za tepla (including the influence of softening processes).
