Summary

The lectures offer the basic knowledges on chemical composition, structure, properties and application of metals and alloys. First part of subject is devoted to interatomic bonds and crystallic structure of metals. The second one deals with influence of external forces on materials, with testing of mechanical and technological properties of materials and is completed by degradation processes (creep, fatigue, corrosion and wearing). Third one is aimed at binary systems, ispecially, iron-carbon diagram, as teoretical basis for understanding of steels a cast irons. In this field the students gain also the knowledges about alloying, thermal treatment and properties of steels. The next part of subject gives the informations about the non-ferrous metals (mainly Al, Cu, Ni, Ti alloys), their properties and applications. The lectures are extended to sintered and progressive metals, such as intermetallics, metal glasses and composites. The last part is orientated into the materials design according to the application purposes and sources of informations, standards and databases. Explanation is completed by the case examples of materials in technical practice. In connestion with lectures, the excercises have a laboratory and control character.
