Course abstract

The aim of the study course is to get acquainted with the classification of construction materials, physical-mechanical properties, structure, application, alloy theory. They get to know the theory of alloys, iron - carbon condition diagram, thermal treatment theory and technology. Students learn of surface fastening of details, to acquire knowledge about alloy steels, non - ferrous metals and alloys, composite materials, non - metals materials, nanomaterials and fundamental principles of selection the materials.

Learning outcomes and their assessment

Knowledge of the properties, heat treatment and application of construction and tool materials. Assessment - test.
Skills to choose materials for making parts and tools. Assessment - test and laboratory work reports.

Competence in the properties, marking and application of mechanical engineering materials and tool materials. As a result of successful completion of the course, the student acquires information about the structure, physical, mechanical, technological and operational properties of materials used in mechanical engineering; on the types and technologies of heat treatment of metals and alloys; on the principles for the selection of mechanical engineering materials. Assessed with successful passing of the exam.
