Summary of the subject: The discipline studies the relationship between the chemical composition, structure and properties of materials, as well as their influence on the properties of thermal, chemical, electromagnetic and other factors. Issues of increasing the durability and reliability of elements of structures that work in conditions of long-term creep are considered. The curriculum contains theoretical information about the basics of materials science, the theory of heat treatment of metals, classification, physico-chemical, technological properties and the use of basic construction, construction and operational materials. This makes it possible to choose them on a scientific basis for the manufacture of various parts of thermal energy and radiation equipment, to prescribe the necessary heat treatment of the corresponding steels and alloys, to make a full and high-quality replacement of materials during equipment repair, to correctly choose and use heat-insulating and sealing materials during installation and repair of equipment in the nuclear industry. The considered basic principles of the selection of structural materials, their production and processing technologies form in students an idea of the achievement of scientific and technical progress in the field of creating new materials, improving technological processes, as well as the skills and abilities of practical determination of the physical and mechanical properties of materials and the directed influence on them.

Assessment methods and criteria: Procedure and criteria for assigning points and grades.
The task of current control is to systematically check the understanding and assimilation of the program material, the performance of laboratory work, the ability to independently work out the writing of a report, abstract, the ability to present certain material publicly, in writing or in electronic format. The preparation, execution and defense of reports on laboratory work are assessed with 2 points for a group laboratory and 4 points for work performed on an individual assignment.
The task of the final examination control is a final check of the depth of the student's assimilation of the program material of the discipline, the logic and relationships between its individual sections, the ability to creatively use the acquired knowledge; the ability to form one's attitude to a certain professional problem arising from the content of the educational component, etc.
Evaluation of oral and written test tasks of examination control depends on the form of the test task:
1. the correct version of the answer to the closed test tasks of the first level of difficulty with one correct answer is evaluated as 4 points, the incorrect one - 0 points. There can be no intermediate assessment for these tasks;
2. correct answers to the closed test tasks of the second and third levels of difficulty with the choice of several correct answers, for matching, nested answers, missing words and the correct sequence, which, depending on the difficulty, are estimated at 7...10 points.
The criteria for evaluating answers and completing tasks are:
• complete disclosure of the issue;
• integrity, systematicity and reasoning;
• logic of presentation, speech culture;
• analytical reasoning, ability to make comparisons, conclusions;
• accuracy of written work.
Evaluation of the student's learning results is carried out according to a 100-point scale
