Course abstract

Students acquire classification, physical - mechanical properties, structure, application of construction, tools and special materials. They get to know the theory of alloys, thermal treatment theory and technology. Students acquire knowledge about alloy steels, non - ferrous metals and alloys, non - metals materials, advanced materials and fundamental principles of selection and application the materials.
