The student interprets the role of metals and alloys in mechatronic practice. The student analyzes chemical bonds, the structure of ideal crystals, and crystallographic calculations. The student uses the characteristics of the crystal, lattice defects, the mechanism of plastic deformation, the plastic deformation of single crystal and polycrystalline, the recrystallization process. The student uses the thermal behavior of metals and alloys, the cooling curve, the state diagrams. The student handles the state diagram of iron-carbon, the equilibrium and non-equilibrium transformations of iron alloys, the basics of heat treatment, and the methods of increasing strength. The student analyzes the meaning of stress and strain characteristics and tensile testing. The student examines the fatigue, fracture, creep processes, the effect of alloys on the properties of steels, the grouping of steels, the hardenability, the hardenability and the heat treatment of different steel types. The student makes a proposal to choose the material and technology needed to manufacture the products. The student manages the basic concepts of plastic forming, plastic forming procedures. The student separates iron-based alloys, non-ferrous and light metals, ceramics and composites. The student distinguishes between the electrical conductivity properties of metallic materials, semiconductors and insulators. The student evaluates materials magnetic for basic magnetic properties. The student ranks the most important soft and hard magnetic materials used in mechatronic practice.
Attitude
The student constantly monitors its work, results and conclusions. The student expands its knowledge about magnetic materials and insulators through continuous acquisition of knowledge. The student is open to the use of information technology tools. The student seeks to become familiar with and routinely use the equipment required to perform material testing measurements. The student develops your ability to provide accurate and error-free problem solving, engineering precision and accuracy. The student publishes its opinions and views without offending others.
Independence and responsibility
The student collaborates with the instructor and fellow students to expand knowledge. The student accepts well-founded professional and other critical remarks. In some situations, as part of a team, the student works with fellow students to solve tasks. With his knowledge, he makes a responsible, informed decision based on his analyzes. The student is committed to the principles and methods of systematic thinking and problem solving.
Teaching methodology
The subject is taught in the form of lectures and laboratory exercises. The lectures basically introduce the competence elements of knowledge to the students using the technique of frontal education. The lectures review the advanced materials of mechatronic applications, their technology and research possibilities. The lectures are complementary to the available written study materials, and individually they are not sufficient to achieve adequate preparation.

General rules
Learning outcomes are assessed on the basis of a year-end written performance measurement (exam). To pass the exam, you must achieve at least 40% of the points. On the one hand, the exam asks for the necessary lexical knowledge, and on the other hand, it focuses on the application of the acquired knowledge, thus focusing on problem recognition and solution. During the performance evaluation, the candidate must apply the knowledge acquired during the laboratory exercises.
Assessment methods
Detailed description of mid-term assessments
The subject does not include assessment performed during the semester period.

| Description: | Learning outcomes are assessed on the basis of a year-end written performance measurement (exam). To pass the exam, you must achieve at least 40% of the points. On the one hand, the exam asks for the necessary lexical knowledge, and on the other hand, it focuses on the application of the acquired knowledge, thus focusing on problem recognition and solution. During the performance evaluation, a specific problem related to its mechatronic applications must be solved or make suggestions for solutions. | |
The weight of mid-term assessments in signing or in final grading
The subject does not include assessment performed during the semester period.
The weight of partial exams in grade
| Type: | Proportion |
|---|---|
| Written partial exam | 100 % |
Determination of the grade
| Grade | ECTS | The grade expressed in percents |
|---|---|---|
| very good (5) | Excellent [A] | above 85 % |
| very good (5) | Very Good [B] | 85 % - 85 % |
| good (4) | Good [C] | 70 % - 85 % |
| satisfactory (3) | Satisfactory [D] | 55 % - 70 % |
| sufficient (2) | Pass [E] | 40 % - 55 % |
| insufficient (1) | Fail [F] | below 40 % |
The lower limit specified for each grade already belongs to that grade.
Attendance and participation requirements
Must be present at at least 70% (rounded down) of lectures.
At least 100% of laboratory practices (rounded down) must be actively attended.
Special rules for improving, retaken and replacement
The special rules for improving, retaken and replacement shall be interpreted and applied in conjunction with the general rules of the CoS (TVSZ).
| Taking into account the previous result in case of improvement, retaken-improvement: | ||
| new result overrides previous result | ||
| Completion of unfinished laboratory exercises: | ||
| missed laboratory practices must be performed in the repeat period | ||
| Repetition of laboratory exercises that performed incorrectly (eg.: mistake in documentation) | ||
| incorrectly performed laboratory practice (e.g. Incomplete/incorrect report) can be corrected upon improved re-submission | ||
