Subject aims expressed by acquired skills and competences

The student will be able to characterize the technology of forging and technological processes for forging of free and die forgings. The student will be able to formulate and analyze the basic mechanical and physical processes occurring in free and die forging and to be able to propose technological procedures for forging of simple free and die-shaped moldings. The student will be able to characterize the principles of controlled forming and cooling and their influence on the structure and mechanical properties of the materials. He will also be able to characterized selected SPD processes including preparation of ultra-fine grain structure.

The course is focused on the theoretical and practical aspects of technological processes of free and die steel forging and non-ferrous metals. Particular attention is paid to the free fitting of dimensional forgings from structural and tool steels and their heat treatment. In the die forging, attention is paid to classical forging technology, buckets, presses and fittings on rotary forging machines. Also, basic theoretical knowledge from the field of preparation of ultraviolet structure, SPD processes and thermo-mechanical processing are presented.
