Physical Metallurgy
Description: It contains theoretical information on the formation of macro-, micro-, sub- and nanostructures of powders (granules) and materials sintered from them. Attention is focused on the features of crystallization processes, segregation in relation to high-speed solidification of granules. A method for calculating the hardening effect of the dispersed hardening mechanism is given. The results of innovative developments in the field of obtaining reactor, medical and precious materials are presented.

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 |

The evaluating policy of learning outcomes by work type
| Type of task | 90-100 | 70-89 | 50-69 | 0-49 |
|---|---|---|---|---|
| Excellent | Good | Satisfactory | Unsatisfactory | |
| Individual tasks | the logical content is presented; the relevance of the topic under consideration is reflected, the main categories are correctly identified; detailed, independent conclusions are formulated in conclusion | the logical content is presented; the relevance of the topic is revealed; there are minor errors and shortcomings in the studied material; in conclusion, general conclusions are formulated | the logical content is presented; the relevance of the topic is not fully disclosed; the theoretical analysis is descriptive, the student did not reflect his own position in relation to the materials under consideration; conclusions are not formulated | the logical content is presented; the relevance of the topic under consideration is reflected, the main categories are correctly identified; detailed, independent conclusions are formulated in conclusion |
| Oral answers to control questions | demonstration of deep and complete knowledge and understanding of the entire volume of the studied material; full understanding of the essence of the concepts, phenomena and patterns, theories, relationships; the ability to make a complete and correct answer based on the studied material; highlight the main points, independently support the answer with specific examples, facts; independently make reasoned analysis, generalize conclusions | knowledge of all the studied program material; a complete and correct answer based on the studied theories; minor errors and shortcomings in the reproduction of the studied material, definitions of concepts, inaccuracies in the use of scientific terms or in conclusions and generalizations; the material is presented in a certain logical sequence, but one blunt error or no more than two flaws is allowed, and the student he can correct them on his own if required or with a little help from a teacher; he has mostly mastered the educational material; confirms the answer with specific examples | there are significant deviations from the topic in the answer; the analysis of the problem provided by the question is fragmentary and incomplete; facts are not always separated from opinions, but the student understands the difference between them | demonstration of deep and complete knowledge and understanding of the entire volume of the studied material; full understanding of the essence of the concepts, phenomena and patterns, theories, relationships; the ability to make a complete and correct answer based on the studied material; highlight the main points, independently support the answer with specific examples, facts; independently make reasoned analysis, generalize conclusions |
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 |
