Amount of credits: 6

Пререквизиты:

• Surface Hardening of Materials

Course Workload:

Component: Component by selection

Cycle: Profiling disciplines

Goal

• students should know: the main types of heat treatment of ferrous and non-ferrous metals, as well as ways to implement them in the conditions of machine-building or metallurgical production. They must have an understanding of the physical and chemical nature of the processes occurring during quenching, tempering, aging, and various annealing processes.

Objective

• Establishing the relationship between the structure, composition, and properties of metals. Study of the theory and practice of various methods of metal hardening that ensure high reliability and durability of machine parts and tools. - Study of the main groups of metal materials, their properties and applications.

Learning outcome: knowledge and understanding

• After studying the course, the master's student must know the classification of the processes of heat treatment of metals and alloys. Optimization of heat treatment modes. Thermal processes during heat treatment.

Learning outcome: applying knowledge and understanding

• The ability to use in research and calculations knowledge about methods of research, analysis, diagnostics and modeling of the properties of substances( materials), physical and chemical processes occurring in materials during their preparation, processing and modification.

Learning outcome: formation of judgments

• Willingness to participate in the development of technological processes for the production and processing of coatings, materials and products made from them, and process control systems.

Learning outcome: communicative abilities

• willingness to cooperate with colleagues, to work in a team; willingness to use the basic laws of the discipline in professional activities, to apply the methods of theoretical and experimental research.

Learning outcome: learning skills or learning abilities

• 1 methodology of scientific knowledge 2 apply scientific methods of cognition at the professional level 3 solutions to standard scientific and professional tasks

Teaching methods

When giving lectures on this discipline, such a non-imitative method of active learning as a "Problem lecture"is used. Before studying the module, a problem is identified, which will be addressed by all the subsequent material of the module. Multimedia presentations are used during the lecture. When performing practical work, the interactive learning method "Case-method" is used: a task is given to undergraduates to prepare for the work; the purpose of the work and the progress of its implementation are discussed with the teacher; the goal is analyzed from different points of view, hypotheses are put forward, conclusions are drawn, and the results obtained are analyzed. The following innovative control methods are used: intermediate and final testing
