Aim
The purpose of the course is to familiarize students with the production, processing, and bonding technologies of technical metals and alloys. The primary focus is on the area of iron-based alloys. Furthermore, the course aims to introduce the students to the effect of the production technologies of various metal products on the basic properties of these material groups (steels, cast irons, light, and non-ferrous metals, metal-based composites, etc.) and to introduce specific design, sustainability and industrial property aspects of these materials.

The student is able to judge the mechanical properties of metallic materials, standard measurement processes of strength, plasticity, and toughness and their influence on the behavior of the material, also in terms of brittle/ductile behavior. The student is able to use the binary alloy phase diagrams of metals, especially the Fe-Fe3C metastable state diagram, and to assess the effects on the properties of the alloy. The student interprets non-equilibrium transformations of steels, isothermal, and continuous diagrams (TTT and CCT diagrams), thus the basic heat treatment processes and their effects. The student interprets the theoretical possibilities and practical methods of metal production, pig iron production, and steel production. The student interprets the alloying elements of steels and their effect on the properties of steels, as well as the groupings of steels, their designation system, their usage, chemical composition, mechanical properties, etc. The student examines casting alloys and casting processes such as: sand casting, precision casting, centrifugal casting, mold casting, pressure casting. Furthermore, powder metallurgy, its steps and products. The student examines the classification of bulk metal forming technologies, deformations, types of forming machines. Bulk metal forming technologies; freeform forging, drop forging, ring forging, round forging, forward rolling, etc. The student examines sheet metal forming technologies, rolling, bending, cutting, punching, deep drawing, metal pressure formability diagram. The student prioritizes the fundamentals of welding, soldering, and cutting. Fusion welding procedures and solid state welding procedures. The student ranks the available properties of light and non-ferrous metals and metal-based composites. Possibilities of increasing strength, their production processes.
Attitude
The student expands his knowledge of heat and surface treatment by continuously acquiring knowledge. The student is open to learning about and using information technology tools. The student strives to get to know the tool system necessary for problem-solving and to use it routinely and safely. The student strives for accurate, effective, and error-free task solutions. The student publishes their opinion and views without offending others.
Independence and responsibility
The student cooperates with the instructor and fellow students in expanding knowledge. The student performs the analysis of the microstructure of metallographic samples independently. The student accepts well-founded critical comments, the basis of his communication is objective and reliable. In some situations - as part of a team - the student cooperates with his colleagues in solving tasks. In their thinking, the student applies the approach of the process and system principles and approaches it with criticism.
Teaching methodology
The lectures basically use the technique of frontal teaching to introduce the students to the information defined by the knowledge competency elements.

Detailed description of mid-term assessments
The subject does not include assessment performed during the semester period.
Detailed description of assessments performed during the examination period
Elements of the exam:
| Oral partial exam | ||
| Obligation: | mandatory (partial) exam unit, failing the unit results in fail (1) exam result | |
| Description: | The oral exam jointly examines and assesses the students' learning results determined by knowledge and ability-type competencies. Accordingly, the summative evaluation assesses the mastery of the designated theoretical knowledge material, as well as the existence of the knowledge acquired during the related preparation and the application of the skills. The oral exam takes place at the time specified in the study performance evaluation plan, during the exam period, and we provide the opportunity for a pre-examination during the extra week if needed. | |
