Hardening technologies for structural materials
Description: To effectively solve various practical problems, it is important to have knowledge about modern methods of obtaining and processing materials, their properties and optimal applications. This course examines the structure and characteristics of metals, alloys, and other structural materials. As a result of mastering the course, students will be able to competently select the most suitable materials for specific products, taking into account their functional requirements.

Goal
- Students gain knowledge of the theoretical foundations of technological processes and methods of processing mechanical engineering structural materials, study modern methods of obtaining these materials, familiarization with the basics of materials science, methods of mechanical, thermal, and chemical strengthening of materials.
Objective
- The course provides students studying materials science and other specialties with information on the structure of metals and alloys, their crystallization features, methods for studying their structure, and determining their mechanical properties. It provides future specialists with general engineering training and helps them master other specialized disciplines.
Learning outcome: knowledge and understanding
- - must learn the basic concepts, conditions and laws of this course; - must be able to set research problems, goals and objectives in specific physical conditions; - must be able to correctly understand and translate information in order to make optimal decisions; - must be able to relate the solutions that arise in the practice and practical problems of the specialty to phenomena of a physical nature and find the correct physical solution.
Learning outcome: applying knowledge and understanding
- Ability to apply knowledge of the structure, properties, and processing methods of structural materials, as well as principles of material selection, to solve practical engineering tasks.
Learning outcome: formation of judgments
- Ability to make well-reasoned judgments on the selection of effective strengthening technologies (thermal, chemical-thermal treatment, plastic deformation), based on their influence on material properties in specific industrial contexts.
Learning outcome: communicative abilities
- readiness to change social, economic, professional roles, geographical and social mobility in the context of the dynamics of change, to continue training independently.
Learning outcome: learning skills or learning abilities
- Ability to independently acquire new scientific and technical knowledge in the field of strengthening technologies, pursue continuous professional development, and adapt to modern industrial requirements.
Teaching methods
When conducting training sessions, the following educational technologies are provided: - interactive lecture (using the following active forms of learning: guided discussion or conversation; moderation; demonstration of slides or educational films; brainstorming; motivational speech); - building scenarios for various situations based on the specified conditions; - information and communication technology (for example, classes in a computer class using professional software packages); - search and research (independent research activity of students in the learning process); - the solution of educational tasks.
Assessment of the student's knowledge
Teacher oversees various tasks related to ongoing assessment and determines students' current performance twice during each academic period. Ratings 1 and 2 are formulated based on the outcomes of this ongoing assessment. The student's learning achievements are assessed using a 100-point scale, and the final grades P1 and P2 are calculated as the average of their ongoing performance evaluations. The teacher evaluates the student's work throughout the academic period in alignment with the assignment submission schedule for the discipline. The assessment system may incorporate a mix of written and oral, group and individual formats.
| Period | Type of task | Total |
|---|---|---|
| 1 rating | Colloquium | 0-100 |
| Individual tasks | ||
| Intermediate control 1 | ||
| 2 rating | Colloquium | 0-100 |
| Individual tasks | ||
| Intermediate control 2 | ||
| Total control | Exam | 0-100 |
The evaluating policy of learning outcomes by work type
| Type of task | 90-100 | 70-89 | 50-69 | 0-49 |

| Excellent | Good | Satisfactory | Unsatisfactory |
Evaluation form
The student's final grade in the course is calculated on a 100 point grading scale, it includes:
- 40% of the examination result;
- 60% of current control result.
The final grade is calculated by the formula:
| FG = 0,6 | MT1+MT2 | +0,4E |
| 2 |
Where Midterm 1, Midterm 2are digital equivalents of the grades of Midterm 1 and 2;
E is a digital equivalent of the exam grade.
Final alphabetical grade and its equivalent in points:
The letter grading system for students' academic achievements, corresponding to the numerical equivalent on a four-point scale:
| Alphabetical grade | Numerical value | Points (%) | Traditional grade |
|---|---|---|---|
| A | 4.0 | 95-100 | Excellent |
| A- | 3.67 | 90-94 | |
| B+ | 3.33 | 85-89 | Good |
| B | 3.0 | 80-84 | |
| B- | 2.67 | 75-79 | |
| C+ | 2.33 | 70-74 | |
| C | 2.0 | 65-69 | Satisfactory |
| C- | 1.67 | 60-64 | |
| D+ | 1.33 | 55-59 | |
| D | 1.0 | 50-54 | |
| FX | 0.5 | 25-49 | Unsatisfactory |
| F | 0 | 0-24 |
